How to Write a Literature Review | Guide, Examples, & Templates

Published on January 2, 2023 by Shona McCombes . Revised on September 11, 2023.

What is a literature review? A literature review is a survey of scholarly sources on a specific topic. It provides an overview of current knowledge, allowing you to identify relevant theories, methods, and gaps in the existing research that you can later apply to your paper, thesis, or dissertation topic .

There are five key steps to writing a literature review:

• Search for relevant literature
• Evaluate sources
• Identify themes, debates, and gaps
• Outline the structure
• Write your literature review

A good literature review doesn’t just summarize sources—it analyzes, synthesizes , and critically evaluates to give a clear picture of the state of knowledge on the subject.

When you write a thesis , dissertation , or research paper , you will likely have to conduct a literature review to situate your research within existing knowledge. The literature review gives you a chance to:

• Demonstrate your familiarity with the topic and its scholarly context
• Develop a theoretical framework and methodology for your research
• Position your work in relation to other researchers and theorists
• Show how your research addresses a gap or contributes to a debate
• Evaluate the current state of research and demonstrate your knowledge of the scholarly debates around your topic.

Writing literature reviews is a particularly important skill if you want to apply for graduate school or pursue a career in research. We’ve written a step-by-step guide that you can follow below.

Writing literature reviews can be quite challenging! A good starting point could be to look at some examples, depending on what kind of literature review you’d like to write.

• Example literature review #1: “Why Do People Migrate? A Review of the Theoretical Literature” ( Theoretical literature review about the development of economic migration theory from the 1950s to today.)
• Example literature review #2: “Literature review as a research methodology: An overview and guidelines” ( Methodological literature review about interdisciplinary knowledge acquisition and production.)
• Example literature review #3: “The Use of Technology in English Language Learning: A Literature Review” ( Thematic literature review about the effects of technology on language acquisition.)
• Example literature review #4: “Learners’ Listening Comprehension Difficulties in English Language Learning: A Literature Review” ( Chronological literature review about how the concept of listening skills has changed over time.)

Before you begin searching for literature, you need a clearly defined topic .

If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research problem and questions .

Make a list of keywords

Start by creating a list of keywords related to your research question. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list as you discover new keywords in the process of your literature search.

• Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
• Body image, self-perception, self-esteem, mental health
• Generation Z, teenagers, adolescents, youth

Search for relevant sources

Use your keywords to begin searching for sources. Some useful databases to search for journals and articles include:

• Your university’s library catalogue
• Google Scholar
• Project Muse (humanities and social sciences)
• Medline (life sciences and biomedicine)
• EconLit (economics)
• Inspec (physics, engineering and computer science)

You can also use boolean operators to help narrow down your search.

Make sure to read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.

You likely won’t be able to read absolutely everything that has been written on your topic, so it will be necessary to evaluate which sources are most relevant to your research question.

For each publication, ask yourself:

• What question or problem is the author addressing?
• What are the key concepts and how are they defined?
• What are the key theories, models, and methods?
• Does the research use established frameworks or take an innovative approach?
• What are the results and conclusions of the study?
• How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
• What are the strengths and weaknesses of the research?

Make sure the sources you use are credible , and make sure you read any landmark studies and major theories in your field of research.

Take notes and cite your sources

As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.

It is important to keep track of your sources with citations to avoid plagiarism . It can be helpful to make an annotated bibliography , where you compile full citation information and write a paragraph of summary and analysis for each source. This helps you remember what you read and saves time later in the process.

Prevent plagiarism. Run a free check.

To begin organizing your literature review’s argument and structure, be sure you understand the connections and relationships between the sources you’ve read. Based on your reading and notes, you can look for:

• Trends and patterns (in theory, method or results): do certain approaches become more or less popular over time?
• Themes: what questions or concepts recur across the literature?
• Debates, conflicts and contradictions: where do sources disagree?
• Pivotal publications: are there any influential theories or studies that changed the direction of the field?
• Gaps: what is missing from the literature? Are there weaknesses that need to be addressed?

This step will help you work out the structure of your literature review and (if applicable) show how your own research will contribute to existing knowledge.

• Most research has focused on young women.
• There is an increasing interest in the visual aspects of social media.
• But there is still a lack of robust research on highly visual platforms like Instagram and Snapchat—this is a gap that you could address in your own research.

There are various approaches to organizing the body of a literature review. Depending on the length of your literature review, you can combine several of these strategies (for example, your overall structure might be thematic, but each theme is discussed chronologically).

Chronological

The simplest approach is to trace the development of the topic over time. However, if you choose this strategy, be careful to avoid simply listing and summarizing sources in order.

Try to analyze patterns, turning points and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.

If you have found some recurring central themes, you can organize your literature review into subsections that address different aspects of the topic.

For example, if you are reviewing literature about inequalities in migrant health outcomes, key themes might include healthcare policy, language barriers, cultural attitudes, legal status, and economic access.

Methodological

If you draw your sources from different disciplines or fields that use a variety of research methods , you might want to compare the results and conclusions that emerge from different approaches. For example:

• Look at what results have emerged in qualitative versus quantitative research
• Discuss how the topic has been approached by empirical versus theoretical scholarship
• Divide the literature into sociological, historical, and cultural sources

Theoretical

A literature review is often the foundation for a theoretical framework . You can use it to discuss various theories, models, and definitions of key concepts.

You might argue for the relevance of a specific theoretical approach, or combine various theoretical concepts to create a framework for your research.

Like any other academic text , your literature review should have an introduction , a main body, and a conclusion . What you include in each depends on the objective of your literature review.

The introduction should clearly establish the focus and purpose of the literature review.

Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.

As you write, you can follow these tips:

• Summarize and synthesize: give an overview of the main points of each source and combine them into a coherent whole
• Analyze and interpret: don’t just paraphrase other researchers — add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
• Critically evaluate: mention the strengths and weaknesses of your sources
• Write in well-structured paragraphs: use transition words and topic sentences to draw connections, comparisons and contrasts

In the conclusion, you should summarize the key findings you have taken from the literature and emphasize their significance.

A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .

It is often written as part of a thesis, dissertation , or research paper , in order to situate your work in relation to existing knowledge.

There are several reasons to conduct a literature review at the beginning of a research project:

• To familiarize yourself with the current state of knowledge on your topic
• To ensure that you’re not just repeating what others have already done
• To identify gaps in knowledge and unresolved problems that your research can address
• To develop your theoretical framework and methodology
• To provide an overview of the key findings and debates on the topic

Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.

The literature review usually comes near the beginning of your thesis or dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .

A literature review is a survey of credible sources on a topic, often used in dissertations , theses, and research papers . Literature reviews give an overview of knowledge on a subject, helping you identify relevant theories and methods, as well as gaps in existing research. Literature reviews are set up similarly to other  academic texts , with an introduction , a main body, and a conclusion .

An  annotated bibliography is a list of  source references that has a short description (called an annotation ) for each of the sources. It is often assigned as part of the research process for a  paper .

Ten Simple Rules for Writing a Literature Review

Marco pautasso.

1 Centre for Functional and Evolutionary Ecology (CEFE), CNRS, Montpellier, France

2 Centre for Biodiversity Synthesis and Analysis (CESAB), FRB, Aix-en-Provence, France

Literature reviews are in great demand in most scientific fields. Their need stems from the ever-increasing output of scientific publications [1] . For example, compared to 1991, in 2008 three, eight, and forty times more papers were indexed in Web of Science on malaria, obesity, and biodiversity, respectively [2] . Given such mountains of papers, scientists cannot be expected to examine in detail every single new paper relevant to their interests [3] . Thus, it is both advantageous and necessary to rely on regular summaries of the recent literature. Although recognition for scientists mainly comes from primary research, timely literature reviews can lead to new synthetic insights and are often widely read [4] . For such summaries to be useful, however, they need to be compiled in a professional way [5] .

When starting from scratch, reviewing the literature can require a titanic amount of work. That is why researchers who have spent their career working on a certain research issue are in a perfect position to review that literature. Some graduate schools are now offering courses in reviewing the literature, given that most research students start their project by producing an overview of what has already been done on their research issue [6] . However, it is likely that most scientists have not thought in detail about how to approach and carry out a literature review.

Reviewing the literature requires the ability to juggle multiple tasks, from finding and evaluating relevant material to synthesising information from various sources, from critical thinking to paraphrasing, evaluating, and citation skills [7] . In this contribution, I share ten simple rules I learned working on about 25 literature reviews as a PhD and postdoctoral student. Ideas and insights also come from discussions with coauthors and colleagues, as well as feedback from reviewers and editors.

Rule 1: Define a Topic and Audience

How to choose which topic to review? There are so many issues in contemporary science that you could spend a lifetime of attending conferences and reading the literature just pondering what to review. On the one hand, if you take several years to choose, several other people may have had the same idea in the meantime. On the other hand, only a well-considered topic is likely to lead to a brilliant literature review [8] . The topic must at least be:

• interesting to you (ideally, you should have come across a series of recent papers related to your line of work that call for a critical summary),
• an important aspect of the field (so that many readers will be interested in the review and there will be enough material to write it), and
• a well-defined issue (otherwise you could potentially include thousands of publications, which would make the review unhelpful).

Ideas for potential reviews may come from papers providing lists of key research questions to be answered [9] , but also from serendipitous moments during desultory reading and discussions. In addition to choosing your topic, you should also select a target audience. In many cases, the topic (e.g., web services in computational biology) will automatically define an audience (e.g., computational biologists), but that same topic may also be of interest to neighbouring fields (e.g., computer science, biology, etc.).

Rule 2: Search and Re-search the Literature

After having chosen your topic and audience, start by checking the literature and downloading relevant papers. Five pieces of advice here:

• keep track of the search items you use (so that your search can be replicated [10] ),
• keep a list of papers whose pdfs you cannot access immediately (so as to retrieve them later with alternative strategies),
• use a paper management system (e.g., Mendeley, Papers, Qiqqa, Sente),
• define early in the process some criteria for exclusion of irrelevant papers (these criteria can then be described in the review to help define its scope), and
• do not just look for research papers in the area you wish to review, but also seek previous reviews.

The chances are high that someone will already have published a literature review ( Figure 1 ), if not exactly on the issue you are planning to tackle, at least on a related topic. If there are already a few or several reviews of the literature on your issue, my advice is not to give up, but to carry on with your own literature review,

The bottom-right situation (many literature reviews but few research papers) is not just a theoretical situation; it applies, for example, to the study of the impacts of climate change on plant diseases, where there appear to be more literature reviews than research studies [33] .

• discussing in your review the approaches, limitations, and conclusions of past reviews,
• trying to find a new angle that has not been covered adequately in the previous reviews, and
• incorporating new material that has inevitably accumulated since their appearance.

When searching the literature for pertinent papers and reviews, the usual rules apply:

• be thorough,
• use different keywords and database sources (e.g., DBLP, Google Scholar, ISI Proceedings, JSTOR Search, Medline, Scopus, Web of Science), and
• look at who has cited past relevant papers and book chapters.

Rule 3: Take Notes While Reading

If you read the papers first, and only afterwards start writing the review, you will need a very good memory to remember who wrote what, and what your impressions and associations were while reading each single paper. My advice is, while reading, to start writing down interesting pieces of information, insights about how to organize the review, and thoughts on what to write. This way, by the time you have read the literature you selected, you will already have a rough draft of the review.

Of course, this draft will still need much rewriting, restructuring, and rethinking to obtain a text with a coherent argument [11] , but you will have avoided the danger posed by staring at a blank document. Be careful when taking notes to use quotation marks if you are provisionally copying verbatim from the literature. It is advisable then to reformulate such quotes with your own words in the final draft. It is important to be careful in noting the references already at this stage, so as to avoid misattributions. Using referencing software from the very beginning of your endeavour will save you time.

Rule 4: Choose the Type of Review You Wish to Write

After having taken notes while reading the literature, you will have a rough idea of the amount of material available for the review. This is probably a good time to decide whether to go for a mini- or a full review. Some journals are now favouring the publication of rather short reviews focusing on the last few years, with a limit on the number of words and citations. A mini-review is not necessarily a minor review: it may well attract more attention from busy readers, although it will inevitably simplify some issues and leave out some relevant material due to space limitations. A full review will have the advantage of more freedom to cover in detail the complexities of a particular scientific development, but may then be left in the pile of the very important papers “to be read” by readers with little time to spare for major monographs.

There is probably a continuum between mini- and full reviews. The same point applies to the dichotomy of descriptive vs. integrative reviews. While descriptive reviews focus on the methodology, findings, and interpretation of each reviewed study, integrative reviews attempt to find common ideas and concepts from the reviewed material [12] . A similar distinction exists between narrative and systematic reviews: while narrative reviews are qualitative, systematic reviews attempt to test a hypothesis based on the published evidence, which is gathered using a predefined protocol to reduce bias [13] , [14] . When systematic reviews analyse quantitative results in a quantitative way, they become meta-analyses. The choice between different review types will have to be made on a case-by-case basis, depending not just on the nature of the material found and the preferences of the target journal(s), but also on the time available to write the review and the number of coauthors [15] .

Rule 5: Keep the Review Focused, but Make It of Broad Interest

Whether your plan is to write a mini- or a full review, it is good advice to keep it focused 16 , 17 . Including material just for the sake of it can easily lead to reviews that are trying to do too many things at once. The need to keep a review focused can be problematic for interdisciplinary reviews, where the aim is to bridge the gap between fields [18] . If you are writing a review on, for example, how epidemiological approaches are used in modelling the spread of ideas, you may be inclined to include material from both parent fields, epidemiology and the study of cultural diffusion. This may be necessary to some extent, but in this case a focused review would only deal in detail with those studies at the interface between epidemiology and the spread of ideas.

While focus is an important feature of a successful review, this requirement has to be balanced with the need to make the review relevant to a broad audience. This square may be circled by discussing the wider implications of the reviewed topic for other disciplines.

Rule 6: Be Critical and Consistent

Reviewing the literature is not stamp collecting. A good review does not just summarize the literature, but discusses it critically, identifies methodological problems, and points out research gaps [19] . After having read a review of the literature, a reader should have a rough idea of:

• the major achievements in the reviewed field,
• the main areas of debate, and
• the outstanding research questions.

It is challenging to achieve a successful review on all these fronts. A solution can be to involve a set of complementary coauthors: some people are excellent at mapping what has been achieved, some others are very good at identifying dark clouds on the horizon, and some have instead a knack at predicting where solutions are going to come from. If your journal club has exactly this sort of team, then you should definitely write a review of the literature! In addition to critical thinking, a literature review needs consistency, for example in the choice of passive vs. active voice and present vs. past tense.

Rule 7: Find a Logical Structure

Like a well-baked cake, a good review has a number of telling features: it is worth the reader's time, timely, systematic, well written, focused, and critical. It also needs a good structure. With reviews, the usual subdivision of research papers into introduction, methods, results, and discussion does not work or is rarely used. However, a general introduction of the context and, toward the end, a recapitulation of the main points covered and take-home messages make sense also in the case of reviews. For systematic reviews, there is a trend towards including information about how the literature was searched (database, keywords, time limits) [20] .

How can you organize the flow of the main body of the review so that the reader will be drawn into and guided through it? It is generally helpful to draw a conceptual scheme of the review, e.g., with mind-mapping techniques. Such diagrams can help recognize a logical way to order and link the various sections of a review [21] . This is the case not just at the writing stage, but also for readers if the diagram is included in the review as a figure. A careful selection of diagrams and figures relevant to the reviewed topic can be very helpful to structure the text too [22] .

Rule 8: Make Use of Feedback

Reviews of the literature are normally peer-reviewed in the same way as research papers, and rightly so [23] . As a rule, incorporating feedback from reviewers greatly helps improve a review draft. Having read the review with a fresh mind, reviewers may spot inaccuracies, inconsistencies, and ambiguities that had not been noticed by the writers due to rereading the typescript too many times. It is however advisable to reread the draft one more time before submission, as a last-minute correction of typos, leaps, and muddled sentences may enable the reviewers to focus on providing advice on the content rather than the form.

Feedback is vital to writing a good review, and should be sought from a variety of colleagues, so as to obtain a diversity of views on the draft. This may lead in some cases to conflicting views on the merits of the paper, and on how to improve it, but such a situation is better than the absence of feedback. A diversity of feedback perspectives on a literature review can help identify where the consensus view stands in the landscape of the current scientific understanding of an issue [24] .

Rule 9: Include Your Own Relevant Research, but Be Objective

In many cases, reviewers of the literature will have published studies relevant to the review they are writing. This could create a conflict of interest: how can reviewers report objectively on their own work [25] ? Some scientists may be overly enthusiastic about what they have published, and thus risk giving too much importance to their own findings in the review. However, bias could also occur in the other direction: some scientists may be unduly dismissive of their own achievements, so that they will tend to downplay their contribution (if any) to a field when reviewing it.

In general, a review of the literature should neither be a public relations brochure nor an exercise in competitive self-denial. If a reviewer is up to the job of producing a well-organized and methodical review, which flows well and provides a service to the readership, then it should be possible to be objective in reviewing one's own relevant findings. In reviews written by multiple authors, this may be achieved by assigning the review of the results of a coauthor to different coauthors.

Rule 10: Be Up-to-Date, but Do Not Forget Older Studies

Given the progressive acceleration in the publication of scientific papers, today's reviews of the literature need awareness not just of the overall direction and achievements of a field of inquiry, but also of the latest studies, so as not to become out-of-date before they have been published. Ideally, a literature review should not identify as a major research gap an issue that has just been addressed in a series of papers in press (the same applies, of course, to older, overlooked studies (“sleeping beauties” [26] )). This implies that literature reviewers would do well to keep an eye on electronic lists of papers in press, given that it can take months before these appear in scientific databases. Some reviews declare that they have scanned the literature up to a certain point in time, but given that peer review can be a rather lengthy process, a full search for newly appeared literature at the revision stage may be worthwhile. Assessing the contribution of papers that have just appeared is particularly challenging, because there is little perspective with which to gauge their significance and impact on further research and society.

Inevitably, new papers on the reviewed topic (including independently written literature reviews) will appear from all quarters after the review has been published, so that there may soon be the need for an updated review. But this is the nature of science [27] – [32] . I wish everybody good luck with writing a review of the literature.

Writing a Literature Review

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

A literature review is a document or section of a document that collects key sources on a topic and discusses those sources in conversation with each other (also called synthesis ). The lit review is an important genre in many disciplines, not just literature (i.e., the study of works of literature such as novels and plays). When we say “literature review” or refer to “the literature,” we are talking about the research ( scholarship ) in a given field. You will often see the terms “the research,” “the scholarship,” and “the literature” used mostly interchangeably.

Where, when, and why would I write a lit review?

There are a number of different situations where you might write a literature review, each with slightly different expectations; different disciplines, too, have field-specific expectations for what a literature review is and does. For instance, in the humanities, authors might include more overt argumentation and interpretation of source material in their literature reviews, whereas in the sciences, authors are more likely to report study designs and results in their literature reviews; these differences reflect these disciplines’ purposes and conventions in scholarship. You should always look at examples from your own discipline and talk to professors or mentors in your field to be sure you understand your discipline’s conventions, for literature reviews as well as for any other genre.

A literature review can be a part of a research paper or scholarly article, usually falling after the introduction and before the research methods sections. In these cases, the lit review just needs to cover scholarship that is important to the issue you are writing about; sometimes it will also cover key sources that informed your research methodology.

Lit reviews can also be standalone pieces, either as assignments in a class or as publications. In a class, a lit review may be assigned to help students familiarize themselves with a topic and with scholarship in their field, get an idea of the other researchers working on the topic they’re interested in, find gaps in existing research in order to propose new projects, and/or develop a theoretical framework and methodology for later research. As a publication, a lit review usually is meant to help make other scholars’ lives easier by collecting and summarizing, synthesizing, and analyzing existing research on a topic. This can be especially helpful for students or scholars getting into a new research area, or for directing an entire community of scholars toward questions that have not yet been answered.

What are the parts of a lit review?

Most lit reviews use a basic introduction-body-conclusion structure; if your lit review is part of a larger paper, the introduction and conclusion pieces may be just a few sentences while you focus most of your attention on the body. If your lit review is a standalone piece, the introduction and conclusion take up more space and give you a place to discuss your goals, research methods, and conclusions separately from where you discuss the literature itself.

Introduction:

• An introductory paragraph that explains what your working topic and thesis is
• A forecast of key topics or texts that will appear in the review
• Potentially, a description of how you found sources and how you analyzed them for inclusion and discussion in the review (more often found in published, standalone literature reviews than in lit review sections in an article or research paper)
• Summarize and synthesize: Give an overview of the main points of each source and combine them into a coherent whole
• Analyze and interpret: Don’t just paraphrase other researchers – add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
• Critically Evaluate: Mention the strengths and weaknesses of your sources
• Write in well-structured paragraphs: Use transition words and topic sentence to draw connections, comparisons, and contrasts.

Conclusion:

• Summarize the key findings you have taken from the literature and emphasize their significance
• Connect it back to your primary research question

How should I organize my lit review?

Lit reviews can take many different organizational patterns depending on what you are trying to accomplish with the review. Here are some examples:

• Chronological : The simplest approach is to trace the development of the topic over time, which helps familiarize the audience with the topic (for instance if you are introducing something that is not commonly known in your field). If you choose this strategy, be careful to avoid simply listing and summarizing sources in order. Try to analyze the patterns, turning points, and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred (as mentioned previously, this may not be appropriate in your discipline — check with a teacher or mentor if you’re unsure).
• Thematic : If you have found some recurring central themes that you will continue working with throughout your piece, you can organize your literature review into subsections that address different aspects of the topic. For example, if you are reviewing literature about women and religion, key themes can include the role of women in churches and the religious attitude towards women.
• Qualitative versus quantitative research
• Empirical versus theoretical scholarship
• Divide the research by sociological, historical, or cultural sources
• Theoretical : In many humanities articles, the literature review is the foundation for the theoretical framework. You can use it to discuss various theories, models, and definitions of key concepts. You can argue for the relevance of a specific theoretical approach or combine various theorical concepts to create a framework for your research.

What are some strategies or tips I can use while writing my lit review?

Any lit review is only as good as the research it discusses; make sure your sources are well-chosen and your research is thorough. Don’t be afraid to do more research if you discover a new thread as you’re writing. More info on the research process is available in our "Conducting Research" resources .

As you’re doing your research, create an annotated bibliography ( see our page on the this type of document ). Much of the information used in an annotated bibliography can be used also in a literature review, so you’ll be not only partially drafting your lit review as you research, but also developing your sense of the larger conversation going on among scholars, professionals, and any other stakeholders in your topic.

Usually you will need to synthesize research rather than just summarizing it. This means drawing connections between sources to create a picture of the scholarly conversation on a topic over time. Many student writers struggle to synthesize because they feel they don’t have anything to add to the scholars they are citing; here are some strategies to help you:

• It often helps to remember that the point of these kinds of syntheses is to show your readers how you understand your research, to help them read the rest of your paper.
• Writing teachers often say synthesis is like hosting a dinner party: imagine all your sources are together in a room, discussing your topic. What are they saying to each other?
• Look at the in-text citations in each paragraph. Are you citing just one source for each paragraph? This usually indicates summary only. When you have multiple sources cited in a paragraph, you are more likely to be synthesizing them (not always, but often
• Read more about synthesis here.

The most interesting literature reviews are often written as arguments (again, as mentioned at the beginning of the page, this is discipline-specific and doesn’t work for all situations). Often, the literature review is where you can establish your research as filling a particular gap or as relevant in a particular way. You have some chance to do this in your introduction in an article, but the literature review section gives a more extended opportunity to establish the conversation in the way you would like your readers to see it. You can choose the intellectual lineage you would like to be part of and whose definitions matter most to your thinking (mostly humanities-specific, but this goes for sciences as well). In addressing these points, you argue for your place in the conversation, which tends to make the lit review more compelling than a simple reporting of other sources.

How To Write A Literature Review - A Complete Guide

Table of Contents

A literature review is much more than just another section in your research paper. It forms the very foundation of your research. It is a formal piece of writing where you analyze the existing theoretical framework, principles, and assumptions and use that as a base to shape your approach to the research question.

Curating and drafting a solid literature review section not only lends more credibility to your research paper but also makes your research tighter and better focused. But, writing literature reviews is a difficult task. It requires extensive reading, plus you have to consider market trends and technological and political changes, which tend to change in the blink of an eye.

Now streamline your literature review process with the help of SciSpace Copilot. With this AI research assistant, you can efficiently synthesize and analyze a vast amount of information, identify key themes and trends, and uncover gaps in the existing research. Get real-time explanations, summaries, and answers to your questions for the paper you're reviewing, making navigating and understanding the complex literature landscape easier.

In this comprehensive guide, we will explore everything from the definition of a literature review, its appropriate length, various types of literature reviews, and how to write one.

What is a literature review?

A literature review is a collation of survey, research, critical evaluation, and assessment of the existing literature in a preferred domain.

Eminent researcher and academic Arlene Fink, in her book Conducting Research Literature Reviews , defines it as the following:

“A literature review surveys books, scholarly articles, and any other sources relevant to a particular issue, area of research, or theory, and by so doing, provides a description, summary, and critical evaluation of these works in relation to the research problem being investigated.

Literature reviews are designed to provide an overview of sources you have explored while researching a particular topic, and to demonstrate to your readers how your research fits within a larger field of study.”

Simply put, a literature review can be defined as a critical discussion of relevant pre-existing research around your research question and carving out a definitive place for your study in the existing body of knowledge. Literature reviews can be presented in multiple ways: a section of an article, the whole research paper itself, or a chapter of your thesis.

A literature review does function as a summary of sources, but it also allows you to analyze further, interpret, and examine the stated theories, methods, viewpoints, and, of course, the gaps in the existing content.

As an author, you can discuss and interpret the research question and its various aspects and debate your adopted methods to support the claim.

What is the purpose of a literature review?

A literature review is meant to help your readers understand the relevance of your research question and where it fits within the existing body of knowledge. As a researcher, you should use it to set the context, build your argument, and establish the need for your study.

What is the importance of a literature review?

The literature review is a critical part of research papers because it helps you:

• Gain an in-depth understanding of your research question and the surrounding area
• Convey that you have a thorough understanding of your research area and are up-to-date with the latest changes and advancements
• Establish how your research is connected or builds on the existing body of knowledge and how it could contribute to further research
• Elaborate on the validity and suitability of your theoretical framework and research methodology
• Identify and highlight gaps and shortcomings in the existing body of knowledge and how things need to change
• Convey to readers how your study is different or how it contributes to the research area

How long should a literature review be?

Ideally, the literature review should take up 15%-40% of the total length of your manuscript. So, if you have a 10,000-word research paper, the minimum word count could be 1500.

Your literature review format depends heavily on the kind of manuscript you are writing — an entire chapter in case of doctoral theses, a part of the introductory section in a research article, to a full-fledged review article that examines the previously published research on a topic.

Another determining factor is the type of research you are doing. The literature review section tends to be longer for secondary research projects than primary research projects.

What are the different types of literature reviews?

All literature reviews are not the same. There are a variety of possible approaches that you can take. It all depends on the type of research you are pursuing.

Here are the different types of literature reviews:

Argumentative review

It is called an argumentative review when you carefully present literature that only supports or counters a specific argument or premise to establish a viewpoint.

Integrative review

It is a type of literature review focused on building a comprehensive understanding of a topic by combining available theoretical frameworks and empirical evidence.

Methodological review

This approach delves into the ''how'' and the ''what" of the research question —  you cannot look at the outcome in isolation; you should also review the methodology used.

Systematic review

This form consists of an overview of existing evidence pertinent to a clearly formulated research question, which uses pre-specified and standardized methods to identify and critically appraise relevant research and collect, report, and analyze data from the studies included in the review.

Meta-analysis review

Meta-analysis uses statistical methods to summarize the results of independent studies. By combining information from all relevant studies, meta-analysis can provide more precise estimates of the effects than those derived from the individual studies included within a review.

Historical review

Historical literature reviews focus on examining research throughout a period, often starting with the first time an issue, concept, theory, or phenomenon emerged in the literature, then tracing its evolution within the scholarship of a discipline. The purpose is to place research in a historical context to show familiarity with state-of-the-art developments and identify future research's likely directions.

Theoretical Review

This form aims to examine the corpus of theory accumulated regarding an issue, concept, theory, and phenomenon. The theoretical literature review helps to establish what theories exist, the relationships between them, the degree the existing approaches have been investigated, and to develop new hypotheses to be tested.

Scoping Review

The Scoping Review is often used at the beginning of an article, dissertation, or research proposal. It is conducted before the research to highlight gaps in the existing body of knowledge and explains why the project should be greenlit.

State-of-the-Art Review

The State-of-the-Art review is conducted periodically, focusing on the most recent research. It describes what is currently known, understood, or agreed upon regarding the research topic and highlights where there are still disagreements.

Can you use the first person in a literature review?

When writing literature reviews, you should avoid the usage of first-person pronouns. It means that instead of "I argue that" or "we argue that," the appropriate expression would be "this research paper argues that."

Do you need an abstract for a literature review?

Ideally, yes. It is always good to have a condensed summary that is self-contained and independent of the rest of your review. As for how to draft one, you can follow the same fundamental idea when preparing an abstract for a literature review. It should also include:

• The research topic and your motivation behind selecting it
• A one-sentence thesis statement
• An explanation of the kinds of literature featured in the review
• Summary of what you've learned
• Conclusions you drew from the literature you reviewed
• Potential implications and future scope for research

Here's an example of the abstract of a literature review

Is a literature review written in the past tense?

Yes, the literature review should ideally be written in the past tense. You should not use the present or future tense when writing one. The exceptions are when you have statements describing events that happened earlier than the literature you are reviewing or events that are currently occurring; then, you can use the past perfect or present perfect tenses.

How many sources for a literature review?

There are multiple approaches to deciding how many sources to include in a literature review section. The first approach would be to look level you are at as a researcher. For instance, a doctoral thesis might need 60+ sources. In contrast, you might only need to refer to 5-15 sources at the undergraduate level.

The second approach is based on the kind of literature review you are doing — whether it is merely a chapter of your paper or if it is a self-contained paper in itself. When it is just a chapter, sources should equal the total number of pages in your article's body. In the second scenario, you need at least three times as many sources as there are pages in your work.

Quick tips on how to write a literature review

To know how to write a literature review, you must clearly understand its impact and role in establishing your work as substantive research material.

You need to follow the below-mentioned steps, to write a literature review:

• Outline the purpose behind the literature review
• Search relevant literature
• Examine and assess the relevant resources
• Discover connections by drawing deep insights from the resources
• Structure planning to write a good literature review

1. Outline and identify the purpose of  a literature review

As a first step on how to write a literature review, you must know what the research question or topic is and what shape you want your literature review to take. Ensure you understand the research topic inside out, or else seek clarifications. You must be able to the answer below questions before you start:

• How many sources do I need to include?
• What kind of sources should I analyze?
• How much should I critically evaluate each source?
• Should I summarize, synthesize or offer a critique of the sources?
• Do I need to include any background information or definitions?

Additionally, you should know that the narrower your research topic is, the swifter it will be for you to restrict the number of sources to be analyzed.

2. Search relevant literature

Dig deeper into search engines to discover what has already been published around your chosen topic. Make sure you thoroughly go through appropriate reference sources like books, reports, journal articles, government docs, and web-based resources.

You must prepare a list of keywords and their different variations. You can start your search from any library’s catalog, provided you are an active member of that institution. The exact keywords can be extended to widen your research over other databases and academic search engines like:

• Google Scholar
• Microsoft Academic
• Science.gov

Besides, it is not advisable to go through every resource word by word. Alternatively, what you can do is you can start by reading the abstract and then decide whether that source is relevant to your research or not.

Additionally, you must spend surplus time assessing the quality and relevance of resources. It would help if you tried preparing a list of citations to ensure that there lies no repetition of authors, publications, or articles in the literature review.

3. Examine and assess the sources

It is nearly impossible for you to go through every detail in the research article. So rather than trying to fetch every detail, you have to analyze and decide which research sources resemble closest and appear relevant to your chosen domain.

While analyzing the sources, you should look to find out answers to questions like:

• What question or problem has the author been describing and debating?
• What is the definition of critical aspects?
• How well the theories, approach, and methodology have been explained?
• Whether the research theory used some conventional or new innovative approach?
• How relevant are the key findings of the work?
• In what ways does it relate to other sources on the same topic?
• What challenges does this research paper pose to the existing theory
• What are the possible contributions or benefits it adds to the subject domain?

Be always mindful that you refer only to credible and authentic resources. It would be best if you always take references from different publications to validate your theory.

Always keep track of important information or data you can present in your literature review right from the beginning. It will help steer your path from any threats of plagiarism and also make it easier to curate an annotated bibliography or reference section.

4. Discover connections

At this stage, you must start deciding on the argument and structure of your literature review. To accomplish this, you must discover and identify the relations and connections between various resources while drafting your abstract.

A few aspects that you should be aware of while writing a literature review include:

• Rise to prominence: Theories and methods that have gained reputation and supporters over time.
• Constant scrutiny: Concepts or theories that repeatedly went under examination.
• Contradictions and conflicts: Theories, both the supporting and the contradictory ones, for the research topic.
• Knowledge gaps: What exactly does it fail to address, and how to bridge them with further research?
• Influential resources: Significant research projects available that have been upheld as milestones or perhaps, something that can modify the current trends

Once you join the dots between various past research works, it will be easier for you to draw a conclusion and identify your contribution to the existing knowledge base.

5. Structure planning to write a good literature review

There exist different ways towards planning and executing the structure of a literature review. The format of a literature review varies and depends upon the length of the research.

Like any other research paper, the literature review format must contain three sections: introduction, body, and conclusion. The goals and objectives of the research question determine what goes inside these three sections.

Nevertheless, a good literature review can be structured according to the chronological, thematic, methodological, or theoretical framework approach.

Literature reviews are important resources for scientists. They provide historical context for a field while offering opinions on its future trajectory. Creating them can provide inspiration for one’s own research, as well as some practice in writing. But few scientists are trained in how to write a review — or in what constitutes an excellent one. Even picking the appropriate software to use can be an involved decision (see ‘Tools and techniques’). So Nature asked editors and working scientists with well-cited reviews for their tips.

How to write a literature review in 6 steps

What is a literature review?

How to write a literature review, 1. determine the purpose of your literature review, 2. do an extensive search, 3. evaluate and select literature, 4. analyze the literature, 5. plan the structure of your literature review, 6. write your literature review, other resources to help you write a successful literature review, frequently asked questions about writing a literature review, related articles.

A literature review is an assessment of the sources in a chosen topic of research.

A good literature review does not just summarize sources. It analyzes the state of the field on a given topic and creates a scholarly foundation for you to make your own intervention. It demonstrates to your readers how your research fits within a larger field of study.

In a thesis, a literature review is part of the introduction, but it can also be a separate section. In research papers, a literature review may have its own section or it may be integrated into the introduction, depending on the field.

➡️ Our guide on what is a literature review covers additional basics about literature reviews.

• Identify the main purpose of the literature review.
• Do extensive research.
• Evaluate and select relevant sources.
• Analyze the sources.
• Plan a structure.
• Write the review.

In this section, we review each step of the process of creating a literature review.

In the first step, make sure you know specifically what the assignment is and what form your literature review should take. Read your assignment carefully and seek clarification from your professor or instructor if needed. You should be able to answer the following questions:

• How many sources do I need to include?
• What types of sources should I review?
• Should I evaluate the sources?
• Should I summarize, synthesize or critique sources?
• Do I need to provide any definitions or background information?

In addition to that, be aware that the narrower your topic, the easier it will be to limit the number of sources you need to read in order to get a good overview of the topic.

Now you need to find out what has been written on the topic and search for literature related to your research topic. Make sure to select appropriate source material, which means using academic or scholarly sources , including books, reports, journal articles , government documents and web resources.

➡️ If you’re unsure about how to tell if a source is scholarly, take a look at our guide on how to identify a scholarly source .

Come up with a list of relevant keywords and then start your search with your institution's library catalog, and extend it to other useful databases and academic search engines like:

• Google Scholar
• Science.gov

➡️ Our guide on how to collect data for your thesis might be helpful at this stage of your research as well as the top list of academic search engines .

Once you find a useful article, check out the reference list. It should provide you with even more relevant sources. Also, keep a note of the:

• authors' names
• page numbers

Keeping track of the bibliographic information for each source will save you time when you’re ready to create citations. You could also use a reference manager like Paperpile to automatically save, manage, and cite your references.

Read the literature. You will most likely not be able to read absolutely everything that is out there on the topic. Therefore, read the abstract first to determine whether the rest of the source is worth your time. If the source is relevant for your topic:

• Read it critically.
• Look for the main arguments.
• Take notes as you read.
• Organize your notes using a table, mind map, or other technique.

Now you are ready to analyze the literature you have gathered. While your are working on your analysis, you should ask the following questions:

• What are the key terms, concepts and problems addressed by the author?
• How is this source relevant for my specific topic?
• How is the article structured? What are the major trends and findings?
• What are the conclusions of the study?
• How are the results presented? Is the source credible?
• When comparing different sources, how do they relate to each other? What are the similarities, what are the differences?
• Does the study help me understand the topic better?
• Are there any gaps in the research that need to be filled? How can I further my research as a result of the review?

Tip: Decide on the structure of your literature review before you start writing.

There are various ways to organize your literature review:

• Chronological method : Writing in the chronological method means you are presenting the materials according to when they were published. Follow this approach only if a clear path of research can be identified.
• Thematic review : A thematic review of literature is organized around a topic or issue, rather than the progression of time.
• Publication-based : You can order your sources by publication, if the way you present the order of your sources demonstrates a more important trend. This is the case when a progression revealed from study to study and the practices of researchers have changed and adapted due to the new revelations.
• Methodological approach : A methodological approach focuses on the methods used by the researcher. If you have used sources from different disciplines that use a variety of research methods, you might want to compare the results in light of the different methods and discuss how the topic has been approached from different sides.

Regardless of the structure you chose, a review should always include the following three sections:

• An introduction, which should give the reader an outline of why you are writing the review and explain the relevance of the topic.
• A body, which divides your literature review into different sections. Write in well-structured paragraphs, use transitions and topic sentences and critically analyze each source for how it contributes to the themes you are researching.
• A conclusion , which summarizes the key findings, the main agreements and disagreements in the literature, your overall perspective, and any gaps or areas for further research.

The goal of a literature review is to asses the state of the field on a given topic in preparation for making an intervention.

A literature review should have its own independent section. You should indicate clearly in the table of contents where it can be found, and address this section as “Literature Review.”

There is no set amount of words for a literature review; the length depends on the research. If you are working with a large amount of sources, then it will be long. If your paper does not depend entirely on references, then it will be short.

Most research papers include a literature review. By assessing the available sources in your field of research, you will be able to make a more confident argument about the topic.

Literature reviews are most commonly found in theses and dissertations. However, you find them in research papers as well.

How To Write An A-Grade Literature Review

3 straightforward steps (with examples) + free template.

By: Derek Jansen (MBA) | Expert Reviewed By: Dr. Eunice Rautenbach | October 2019

Quality research is about building onto the existing work of others , “standing on the shoulders of giants”, as Newton put it. The literature review chapter of your dissertation, thesis or research project is where you synthesise this prior work and lay the theoretical foundation for your own research.

Long story short, this chapter is a pretty big deal, which is why you want to make sure you get it right . In this post, I’ll show you exactly how to write a literature review in three straightforward steps, so you can conquer this vital chapter (the smart way).

• Understanding the “ why “
• Finding the relevant literature
• Cataloguing and synthesising the information
• Outlining & writing up your literature review
• Example of a literature review

Before we unpack how to write the literature review chapter, we’ve got to look at the why . To put it bluntly, if you don’t understand the function and purpose of the literature review process, there’s no way you can pull it off well. So, what exactly is the purpose of the literature review?

Well, there are (at least) four core functions:

• For you to gain an understanding (and demonstrate this understanding) of where the research is at currently, what the key arguments and disagreements are.
• For you to identify the gap(s) in the literature and then use this as justification for your own research topic.
• To help you build a conceptual framework for empirical testing (if applicable to your research topic).
• To inform your methodological choices and help you source tried and tested questionnaires (for interviews ) and measurement instruments (for surveys ).

Most students understand the first point but don’t give any thought to the rest. To get the most from the literature review process, you must keep all four points front of mind as you review the literature (more on this shortly), or you’ll land up with a wonky foundation.

Okay – with the why out the way, let’s move on to the how . As mentioned above, writing your literature review is a process, which I’ll break down into three steps:

• Finding the most suitable literature
• Understanding , distilling and organising the literature
• Planning and writing up your literature review chapter

Importantly, you must complete steps one and two before you start writing up your chapter. I know it’s very tempting, but don’t try to kill two birds with one stone and write as you read. You’ll invariably end up wasting huge amounts of time re-writing and re-shaping, or you’ll just land up with a disjointed, hard-to-digest mess . Instead, you need to read first and distil the information, then plan and execute the writing.

Step 1: Find the relevant literature

Naturally, the first step in the literature review journey is to hunt down the existing research that’s relevant to your topic. While you probably already have a decent base of this from your research proposal , you need to expand on this substantially in the dissertation or thesis itself.

Essentially, you need to be looking for any existing literature that potentially helps you answer your research question (or develop it, if that’s not yet pinned down). There are numerous ways to find relevant literature, but I’ll cover my top four tactics here. I’d suggest combining all four methods to ensure that nothing slips past you:

Method 1 – Google Scholar Scrubbing

Google’s academic search engine, Google Scholar , is a great starting point as it provides a good high-level view of the relevant journal articles for whatever keyword you throw at it. Most valuably, it tells you how many times each article has been cited, which gives you an idea of how credible (or at least, popular) it is. Some articles will be free to access, while others will require an account, which brings us to the next method.

Method 2 – University Database Scrounging

Generally, universities provide students with access to an online library, which provides access to many (but not all) of the major journals.

So, if you find an article using Google Scholar that requires paid access (which is quite likely), search for that article in your university’s database – if it’s listed there, you’ll have access. Note that, generally, the search engine capabilities of these databases are poor, so make sure you search for the exact article name, or you might not find it.

Method 3 – Journal Article Snowballing

At the end of every academic journal article, you’ll find a list of references. As with any academic writing, these references are the building blocks of the article, so if the article is relevant to your topic, there’s a good chance a portion of the referenced works will be too. Do a quick scan of the titles and see what seems relevant, then search for the relevant ones in your university’s database.

Method 4 – Dissertation Scavenging

Similar to Method 3 above, you can leverage other students’ dissertations. All you have to do is skim through literature review chapters of existing dissertations related to your topic and you’ll find a gold mine of potential literature. Usually, your university will provide you with access to previous students’ dissertations, but you can also find a much larger selection in the following databases:

• Open Access Theses & Dissertations
• Stanford SearchWorks

Keep in mind that dissertations and theses are not as academically sound as published, peer-reviewed journal articles (because they’re written by students, not professionals), so be sure to check the credibility of any sources you find using this method. You can do this by assessing the citation count of any given article in Google Scholar. If you need help with assessing the credibility of any article, or with finding relevant research in general, you can chat with one of our Research Specialists .

Alright – with a good base of literature firmly under your belt, it’s time to move onto the next step.

Step 2: Log, catalogue and synthesise

Once you’ve built a little treasure trove of articles, it’s time to get reading and start digesting the information – what does it all mean?

While I present steps one and two (hunting and digesting) as sequential, in reality, it’s more of a back-and-forth tango – you’ll read a little , then have an idea, spot a new citation, or a new potential variable, and then go back to searching for articles. This is perfectly natural – through the reading process, your thoughts will develop , new avenues might crop up, and directional adjustments might arise. This is, after all, one of the main purposes of the literature review process (i.e. to familiarise yourself with the current state of research in your field).

As you’re working through your treasure chest, it’s essential that you simultaneously start organising the information. There are three aspects to this:

• Logging reference information
• Building an organised catalogue
• Distilling and synthesising the information

I’ll discuss each of these below:

2.1 – Log the reference information

As you read each article, you should add it to your reference management software. I usually recommend Mendeley for this purpose (see the Mendeley 101 video below), but you can use whichever software you’re comfortable with. Most importantly, make sure you load EVERY article you read into your reference manager, even if it doesn’t seem very relevant at the time.

2.2 – Build an organised catalogue

In the beginning, you might feel confident that you can remember who said what, where, and what their main arguments were. Trust me, you won’t. If you do a thorough review of the relevant literature (as you must!), you’re going to read many, many articles, and it’s simply impossible to remember who said what, when, and in what context . Also, without the bird’s eye view that a catalogue provides, you’ll miss connections between various articles, and have no view of how the research developed over time. Simply put, it’s essential to build your own catalogue of the literature.

I would suggest using Excel to build your catalogue, as it allows you to run filters, colour code and sort – all very useful when your list grows large (which it will). How you lay your spreadsheet out is up to you, but I’d suggest you have the following columns (at minimum):

• Author, date, title – Start with three columns containing this core information. This will make it easy for you to search for titles with certain words, order research by date, or group by author.
• Categories or keywords – You can either create multiple columns, one for each category/theme and then tick the relevant categories, or you can have one column with keywords.
• Key arguments/points – Use this column to succinctly convey the essence of the article, the key arguments and implications thereof for your research.
• Context – Note the socioeconomic context in which the research was undertaken. For example, US-based, respondents aged 25-35, lower- income, etc. This will be useful for making an argument about gaps in the research.
• Methodology – Note which methodology was used and why. Also, note any issues you feel arise due to the methodology. Again, you can use this to make an argument about gaps in the research.
• Quotations – Note down any quoteworthy lines you feel might be useful later.
• Notes – Make notes about anything not already covered. For example, linkages to or disagreements with other theories, questions raised but unanswered, shortcomings or limitations, and so forth.

If you’d like, you can try out our free catalog template here (see screenshot below).

2.3 – Digest and synthesise

Most importantly, as you work through the literature and build your catalogue, you need to synthesise all the information in your own mind – how does it all fit together? Look for links between the various articles and try to develop a bigger picture view of the state of the research. Some important questions to ask yourself are:

• What answers does the existing research provide to my own research questions ?
• Which points do the researchers agree (and disagree) on?
• How has the research developed over time?
• Where do the gaps in the current research lie?

To help you develop a big-picture view and synthesise all the information, you might find mind mapping software such as Freemind useful. Alternatively, if you’re a fan of physical note-taking, investing in a large whiteboard might work for you.

Step 3: Outline and write it up!

Once you’re satisfied that you have digested and distilled all the relevant literature in your mind, it’s time to put pen to paper (or rather, fingers to keyboard). There are two steps here – outlining and writing:

3.1 – Draw up your outline

Having spent so much time reading, it might be tempting to just start writing up without a clear structure in mind. However, it’s critically important to decide on your structure and develop a detailed outline before you write anything. Your literature review chapter needs to present a clear, logical and an easy to follow narrative – and that requires some planning. Don’t try to wing it!

Naturally, you won’t always follow the plan to the letter, but without a detailed outline, you’re more than likely going to end up with a disjointed pile of waffle , and then you’re going to spend a far greater amount of time re-writing, hacking and patching. The adage, “measure twice, cut once” is very suitable here.

In terms of structure, the first decision you’ll have to make is whether you’ll lay out your review thematically (into themes) or chronologically (by date/period). The right choice depends on your topic, research objectives and research questions, which we discuss in this article .

Once that’s decided, you need to draw up an outline of your entire chapter in bullet point format. Try to get as detailed as possible, so that you know exactly what you’ll cover where, how each section will connect to the next, and how your entire argument will develop throughout the chapter. Also, at this stage, it’s a good idea to allocate rough word count limits for each section, so that you can identify word count problems before you’ve spent weeks or months writing!

PS – check out our free literature review chapter template…

3.2 – Get writing

With a detailed outline at your side, it’s time to start writing up (finally!). At this stage, it’s common to feel a bit of writer’s block and find yourself procrastinating under the pressure of finally having to put something on paper. To help with this, remember that the objective of the first draft is not perfection – it’s simply to get your thoughts out of your head and onto paper, after which you can refine them. The structure might change a little, the word count allocations might shift and shuffle, and you might add or remove a section – that’s all okay. Don’t worry about all this on your first draft – just get your thoughts down on paper.

Once you’ve got a full first draft (however rough it may be), step away from it for a day or two (longer if you can) and then come back at it with fresh eyes. Pay particular attention to the flow and narrative – does it fall fit together and flow from one section to another smoothly? Now’s the time to try to improve the linkage from each section to the next, tighten up the writing to be more concise, trim down word count and sand it down into a more digestible read.

Once you’ve done that, give your writing to a friend or colleague who is not a subject matter expert and ask them if they understand the overall discussion. The best way to assess this is to ask them to explain the chapter back to you. This technique will give you a strong indication of which points were clearly communicated and which weren’t. If you’re working with Grad Coach, this is a good time to have your Research Specialist review your chapter.

Finally, tighten it up and send it off to your supervisor for comment. Some might argue that you should be sending your work to your supervisor sooner than this (indeed your university might formally require this), but in my experience, supervisors are extremely short on time (and often patience), so, the more refined your chapter is, the less time they’ll waste on addressing basic issues (which you know about already) and the more time they’ll spend on valuable feedback that will increase your mark-earning potential.

In the video below, we unpack an actual literature review so that you can see how all the core components come together in reality.

Let’s Recap

In this post, we’ve covered how to research and write up a high-quality literature review chapter. Let’s do a quick recap of the key takeaways:

• It is essential to understand the WHY of the literature review before you read or write anything. Make sure you understand the 4 core functions of the process.
• The first step is to hunt down the relevant literature . You can do this using Google Scholar, your university database, the snowballing technique and by reviewing other dissertations and theses.
• Next, you need to log all the articles in your reference manager , build your own catalogue of literature and synthesise all the research.
• Following that, you need to develop a detailed outline of your entire chapter – the more detail the better. Don’t start writing without a clear outline (on paper, not in your head!)
• Write up your first draft in rough form – don’t aim for perfection. Remember, done beats perfect.
• Refine your second draft and get a layman’s perspective on it . Then tighten it up and submit it to your supervisor.

What are Literature Reviews?

So, what is a literature review? "A literature review is an account of what has been published on a topic by accredited scholars and researchers. In writing the literature review, your purpose is to convey to your reader what knowledge and ideas have been established on a topic, and what their strengths and weaknesses are. As a piece of writing, the literature review must be defined by a guiding concept (e.g., your research objective, the problem or issue you are discussing, or your argumentative thesis). It is not just a descriptive list of the material available, or a set of summaries." Taylor, D.  The literature review: A few tips on conducting it . University of Toronto Health Sciences Writing Centre.

Goals of Literature Reviews

What are the goals of creating a Literature Review?  A literature could be written to accomplish different aims:

• To develop a theory or evaluate an existing theory
• To summarize the historical or existing state of a research topic
• Identify a problem in a field of research 

Baumeister, R. F., & Leary, M. R. (1997). Writing narrative literature reviews .  Review of General Psychology , 1 (3), 311-320.

What kinds of sources require a Literature Review?

• A research paper assigned in a course
• A thesis or dissertation
• A grant proposal
• An article intended for publication in a journal

All these instances require you to collect what has been written about your research topic so that you can demonstrate how your own research sheds new light on the topic.

Types of Literature Reviews

What kinds of literature reviews are written?

Narrative review: The purpose of this type of review is to describe the current state of the research on a specific topic/research and to offer a critical analysis of the literature reviewed. Studies are grouped by research/theoretical categories, and themes and trends, strengths and weakness, and gaps are identified. The review ends with a conclusion section which summarizes the findings regarding the state of the research of the specific study, the gaps identify and if applicable, explains how the author's research will address gaps identify in the review and expand the knowledge on the topic reviewed.

• Example : The effect of leave policies on increasing fertility: a systematic review:  10.1057/s41599-022-01270-w

How to Write a Literature Review: Six Steps to Get You from Start to Finish

Writing-a-literature-review-six-steps-to-get-you-from-start-to-finish.

Tanya Golash-Boza, Associate Professor of Sociology, University of California

February 03, 2022

Writing a literature review is often the most daunting part of writing an article, book, thesis, or dissertation. “The literature” seems (and often is) massive. I have found it helpful to be as systematic as possible when completing this gargantuan task.

Sonja Foss and William Walters* describe an efficient and effective way of writing a literature review. Their system provides an excellent guide for getting through the massive amounts of literature for any purpose: in a dissertation, an M.A. thesis, or preparing a research article for publication  in any field of study. Below is a  summary of the steps they outline as well as a step-by-step method for writing a literature review.

How to Write a Literature Review

Step One: Decide on your areas of research:

Before you begin to search for articles or books, decide beforehand what areas you are going to research. Make sure that you only get articles and books in those areas, even if you come across fascinating books in other areas. A literature review I am currently working on, for example, explores barriers to higher education for undocumented students.

Step Two: Search for the literature:

Conduct a comprehensive bibliographic search of books and articles in your area. Read the abstracts online and download and/or print those articles that pertain to your area of research. Find books in the library that are relevant and check them out. Set a specific time frame for how long you will search. It should not take more than two or three dedicated sessions.

Step Three: Find relevant excerpts in your books and articles:

Skim the contents of each book and article and look specifically for these five things:

1. Claims, conclusions, and findings about the constructs you are investigating

2. Definitions of terms

3. Calls for follow-up studies relevant to your project

4. Gaps you notice in the literature

5. Disagreement about the constructs you are investigating

When you find any of these five things, type the relevant excerpt directly into a Word document. Don’t summarize, as summarizing takes longer than simply typing the excerpt. Make sure to note the name of the author and the page number following each excerpt. Do this for each article and book that you have in your stack of literature. When you are done, print out your excerpts.

Step Four: Code the literature:

Get out a pair of scissors and cut each excerpt out. Now, sort the pieces of paper into similar topics. Figure out what the main themes are. Place each excerpt into a themed pile. Make sure each note goes into a pile. If there are excerpts that you can’t figure out where they belong, separate those and go over them again at the end to see if you need new categories. When you finish, place each stack of notes into an envelope labeled with the name of the theme.

Step Five: Create Your Conceptual Schema:

Type, in large font, the name of each of your coded themes. Print this out, and cut the titles into individual slips of paper. Take the slips of paper to a table or large workspace and figure out the best way to organize them. Are there ideas that go together or that are in dialogue with each other? Are there ideas that contradict each other? Move around the slips of paper until you come up with a way of organizing the codes that makes sense. Write the conceptual schema down before you forget or someone cleans up your slips of paper.

Step Six: Begin to Write Your Literature Review:

Choose any section of your conceptual schema to begin with. You can begin anywhere, because you already know the order. Find the envelope with the excerpts in them and lay them on the table in front of you. Figure out a mini-conceptual schema based on that theme by grouping together those excerpts that say the same thing. Use that mini-conceptual schema to write up your literature review based on the excerpts that you have in front of you. Don’t forget to include the citations as you write, so as not to lose track of who said what. Repeat this for each section of your literature review.

Once you complete these six steps, you will have a complete draft of your literature review. The great thing about this process is that it breaks down into manageable steps something that seems enormous: writing a literature review.

I think that Foss and Walter’s system for writing the literature review is ideal for a dissertation, because a Ph.D. candidate has already read widely in his or her field through graduate seminars and comprehensive exams.

It may be more challenging for M.A. students, unless you are already familiar with the literature. It is always hard to figure out how much you need to read for deep meaning, and how much you just need to know what others have said. That balance will depend on how much you already know.

For people writing literature reviews for articles or books, this system also could work, especially when you are writing in a field with which you are already familiar. The mere fact of having a system can make the literature review seem much less daunting, so I recommend this system for anyone who feels overwhelmed by the prospect of writing a literature review.

What is a literature review?

A literature review is an integrated analysis -- not just a summary-- of scholarly writings and other relevant evidence related directly to your research question.  That is, it represents a synthesis of the evidence that provides background information on your topic and shows a association between the evidence and your research question.

A literature review may be a stand alone work or the introduction to a larger research paper, depending on the assignment.  Rely heavily on the guidelines your instructor has given you.

Why is it important?

A literature review is important because it:

• Explains the background of research on a topic.
• Demonstrates why a topic is significant to a subject area.
• Discovers relationships between research studies/ideas.
• Identifies major themes, concepts, and researchers on a topic.
• Identifies critical gaps and points of disagreement.
• Discusses further research questions that logically come out of the previous studies.

APA7 Style resources

APA Style Blog - for those harder to find answers

1. Choose a topic. Define your research question.

Your literature review should be guided by your central research question.  The literature represents background and research developments related to a specific research question, interpreted and analyzed by you in a synthesized way.

• Make sure your research question is not too broad or too narrow.  Is it manageable?
• Begin writing down terms that are related to your question. These will be useful for searches later.
• If you have the opportunity, discuss your topic with your professor and your class mates.

2. Decide on the scope of your review

How many studies do you need to look at? How comprehensive should it be? How many years should it cover? 

• This may depend on your assignment.  How many sources does the assignment require?

3. Select the databases you will use to conduct your searches.

Make a list of the databases you will search. 

Where to find databases:

• use the tabs on this guide
• Find other databases in the Nursing Information Resources web page
• More on the Medical Library web page
• ... and more on the Yale University Library web page

4. Conduct your searches to find the evidence. Keep track of your searches.

• Use the key words in your question, as well as synonyms for those words, as terms in your search. Use the database tutorials for help.
• Save the searches in the databases. This saves time when you want to redo, or modify, the searches. It is also helpful to use as a guide is the searches are not finding any useful results.
• Review the abstracts of research studies carefully. This will save you time.
• Use the bibliographies and references of research studies you find to locate others.
• Check with your professor, or a subject expert in the field, if you are missing any key works in the field.
• Ask your librarian for help at any time.
• Use a citation manager, such as EndNote as the repository for your citations. See the EndNote tutorials for help.

Review the literature

Some questions to help you analyze the research:

• What was the research question of the study you are reviewing? What were the authors trying to discover?
• Was the research funded by a source that could influence the findings?
• What were the research methodologies? Analyze its literature review, the samples and variables used, the results, and the conclusions.
• Does the research seem to be complete? Could it have been conducted more soundly? What further questions does it raise?
• If there are conflicting studies, why do you think that is?
• How are the authors viewed in the field? Has this study been cited? If so, how has it been analyzed?

Tips: 

• Review the abstracts carefully.  
• Keep careful notes so that you may track your thought processes during the research process.
• Create a matrix of the studies for easy analysis, and synthesis, across all of the studies.

How Long Should a Literature Review Be?

4-minute read

• 7th October 2023

If you’re writing a research paper or dissertation , then you know how important it is to include a thorough, comprehensive literature review. But exactly how long should your literature review be in relation to the rest of your work? While there’s no one-size-fits-all answer to that question, there are some factors that will help determine the length of your review. In this post, we’ll discuss what information to include in your literature review and how long it should be.

Keep reading to learn more.

What Is a Literature Review?

A literature review is a critical summary and evaluation of the current resources (e.g., books and journal articles) on a specific topic or research question. It is a crucial part of academic writing, such as dissertations, in all categories and fields. Essentially, literature reviews help contextualize your investigations and show how your work is building on existing research.

No matter how long your literature review is, it should generally:

●  Establish context for your research (i.e., provide relevant background information so your reader understands the historical significance of your study ).

●  Identify gaps in the existing literature (such as unaddressed questions or aspects of your topic).

●  Highlight significant concepts related to your topic.

●  Cite relevant studies.

●  Support your argument.

It’s also essential that a literature review critically analyze the sources cited in your study, considering factors such as sample size, research design, and potential biases. Be sure to structure your literature review using the same referencing style as the rest of your research paper (e.g., APA , Chicago , MLA ).

The length of your literature review depends on several factors, including the scope and purpose of your research. In general, the length of the review should be proportionate to your overall paper. For example, if you’re writing a fifty-thousand-word dissertation, then your literature review will likely be an entire chapter comprising about 20 pages. If it’s for a 15-page research paper, your literature review may only be a few pages.

Here are several factors that could affect the length of your literature review:

●  Institutional guidelines : Always check the guidelines provided by your institution or journal (such as an APA journal ). There may be a specific length or word count required for publication.

●  Scope : If your research topic is narrow and focused, your literature review may be shorter. Conversely, if your topic is broad and encompasses a large body of literature, your review may need to be longer.

●  Field of study : Different academic fields may have different expectations regarding the length of literature reviews. For example, literature reviews in the humanities might be longer than those in the natural sciences.

Also, consider your audience. If your literature review is for a general audience or a class assignment, it can probably be shorter and less specialized. However, if it’s for an academic audience in your field of study, you may need to be more thorough and provide an extensive review of the existing literature.

Most literature reviews follow the same basic structure of an introduction, body, and conclusion. Most of the time, they are part of a larger work, so the introduction and conclusion paragraphs will be relatively brief.

However, if the review is a standalone piece, then your introduction and conclusion will be longer since you will need to discuss your research objectives, methods, and findings as well as analyze the literature used in your study.

Literature reviews

Writing a literature review.

The following guide has been created for you by the  Student Learning Advisory Service . For more detailed guidance and to speak to one of our advisers, please book an  appointment  or join one of our  workshops . Alternatively, have a look at our  SkillBuilder  skills videos.   

Preparing a literature review involves:

• Searching for reliable, accurate and up-to-date material on a topic or subject
• Reading and summarising the key points from this literature
• Synthesising these key ideas, theories and concepts into a summary of what is known
• Discussing and evaluating these ideas, theories and concepts
• Identifying particular areas of debate or controversy
• Preparing the ground for the application of these ideas to new research

Finding and choosing material

Ensure you are clear on what you are looking for. ask yourself:.

• What is the specific question, topic or focus of my assignment?
• What kind of material do I need (e.g. theory, policy, empirical data)?
• What type of literature is available (e.g. journals, books, government documents)?

What kind of literature is particularly authoritative in this academic discipline (e.g. psychology, sociology, pharmacy)?

How much do you need?

This will depend on the length of the dissertation, the nature of the subject, and the level of study (undergraduate, Masters, PhD). As a very rough rule of thumb – you may choose 8-10 significant pieces (books and/or articles) for an 8,000 word dissertation, up to 20 major pieces of work for 12-15,000 words, and so on. Bear in mind that if your dissertation is based mainly around an interaction with existing scholarship you will need a longer literature review than if it is there as a prelude to new empirical research. Use your judgement or ask your supervisor for guidance.

Where to find suitable material

Your literature review should include a balance between substantial academic books, journal articles and other scholarly publications. All these sources should be as up-to-date as possible, with the exception of ‘classic texts’ such as major works written by leading scholars setting out formative ideas and theories central to your subject. There are several ways to locate suitable material:

Module bibliography: for undergraduate dissertations, look first at the bibliography provided with the module documentation. Choose one or two likely looking books or articles and then scan through the bibliographies provided by these authors. Skim read some of this material looking for clues: can you use these leads to identify key theories and authors or track down other appropriate material?

Library catalogue search engine: enter a few key words to capture a range of items, but avoid over-generalisations; if you type in something as broad as ‘social theory’ you are likely to get several thousand results. Be more specific: for example, ‘Heidegger, existentialism’. Ideally, you should narrow the field to obtain just a few dozen results. Skim through these quickly to identity texts which are most likely to contribute to your study.

Library bookshelves: browse the library shelves in the relevant subject area and examine the books that catch your eye. Check the contents and index pages, or skim through the introductions (or abstracts, in the case of journal articles) to see if they contain relevant material, and replace them if not. Don’t be afraid to ask one of the subject librarians for further help. Your supervisor may also be able to point you in the direction of some of the important literature , but remember this is your literature search, not theirs.

Online: for recent journal articles you will almost certainly need to use one of the online search engines. These can be found on the ‘Indexing Services’ button on the Templeman Library website. Kent students based at Medway still need to use the Templeman pages to access online journals, although you can get to these pages through the Drill Hall Library catalogue. Take a look as well at the Subject Guides on both the Templeman and DHL websites.

Check that you have made the right selection by asking:

• Has my search been wide enough to ensure that I have identified all the relevant material, but narrow enough to exclude irrelevant material?
• Is there a good enough sample of literature for the level (PhD, Masters, undergraduate) of my dissertation or thesis?
• Have I considered as many alternative points of view as possible?
• Will the reader find my literature review relevant and useful?

Assessing the literature

Read the material you have chosen carefully, considering the following:

• The key point discussed by the author: is this clearly defined
• What evidence has the author produced to support this central idea?
• How convincing are the reasons given for the author’s point of view?
• Could the evidence be interpreted in other ways?
• What is the author's research method (e.g. qualitative, quantitative, experimental, etc.)?
• What is the author's theoretical framework (e.g. psychological, developmental, feminist)?
• What is the relationship assumed by the author between theory and practice?
• Has the author critically evaluated the other literature in the field?
• Does the author include literature opposing their point of view?
• Is the research data based on a reliable method and accurate information?
• Can you ‘deconstruct’ the argument – identify the gaps or jumps in the logic?
• What are the strengths and limitations of this study?
• What does this book or article contribute to the field or topic?
• What does this book or article contribute to my own topic or thesis?

As you note down the key content of each book or journal article (together with the reference details of each source) record your responses to these questions. You will then be able to summarise each piece of material from two perspectives:     

Content: a brief description of the content of the book or article. Remember, an author will often make just one key point; so, what is the point they are making, and how does it relate to your own research project or assignment?

Critical analysis: an assessment of the relative strengths and weaknesses of the evidence used, and the arguments presented. Has anything conveniently been left out or skated over? Is there a counter-argument, and has the author dealt with this adequately? Can the evidence presented be interpreted another way? Does the author demonstrate any obvious bias which could affect their reliability? Overall, based on the above analysis of the author’s work, how do you evaluate its contribution to the scholarly understanding and knowledge surrounding the topic?    

Structuring the literature review

In a PhD thesis, the literature review typically comprises one chapter (perhaps 8-10,000 words), for a Masters dissertation it may be around 2-3,000 words, and for an undergraduate dissertation it may be no more than 2,000 words. In each case the word count can vary depending on a range of factors and it is always best, if in doubt, to ask your supervisor.

The overall structure of the section or chapter should be like any other: it should have a beginning, middle and end. You will need to guide the reader through the literature review, outlining the strategy you have adopted for selecting the books or articles, presenting the topic theme for the review, then using most of the word limit to analyse the chosen books or articles thoroughly before pulling everything together briefly in the conclusion.

Some people prefer a less linear approach. Instead of simply working through a list of 8-20 items on your book review list, you might want to try a thematic approach, grouping key ideas, facts, concepts or approaches together and then bouncing the ideas off each other. This is a slightly more creative (and interesting) way of producing the review, but a little more risky as it is harder to establish coherence and logical sequencing.

Whichever approach you adopt, make sure everything flows smoothly – that one idea or book leads neatly to the next. Take your reader effortlessly through a sequence of thought that is clear, accurate, precise and interesting. 

Writing up your literature review

As with essays generally, only attempt to write up the literature review when you have completed all the reading and note-taking, and carefully planned its content and structure. Find an appropriate way of introducing the review, then guide the reader through the material clearly and directly, bearing in mind the following:

• Be selective in the number of points you draw out from each piece of literature; remember that one of your objectives is to demonstrate that you can use your judgement to identify what is central and what is secondary.
• Summarise and synthesise – use your own words to sum up what you think is important or controversial about the book or article.
• Never claim more than the evidence will support. Too many dissertations and theses are let down by sweeping generalisations. Be tentative and careful in the way you interpret the evidence.
• Keep your own voice – you are entitled to your own point of view provided it is based on evidence and clear argument.
• At the same time, aim to project an objective and tentative tone by using the 3rd person, (for example, ‘this tends to suggest’, ‘it could be argued’ and so on).
• Even with a literature review you should avoid using too many, or overlong, quotes. Summarise material in your own words as much as possible. Save the quotes for ‘punch-lines’ to drive a particular point home.
• Revise, revise, revise: refine and edit the draft as much as you can. Check for fluency, structure, evidence, criticality and referencing, and don’t forget the basics of good grammar, punctuation and spelling.

What is the purpose of a Literature Review? For a graduate student the purpose of academic writing changes from what it was as an undergraduate. Where undergraduates often write to demonstrate a mastery of existing knowledge, graduate students are considered scholars and move toward creating new knowledge. Writing in graduate school, then, focuses on communicating that new knowledge to others in their field. In order to communicate this knowledge to other scholars, however, it also necessary to explain how that knowledge engages ongoing scholarly conversations in the field.

A literature review is a common genre for many types of writing you’ll have to do as a graduate student and scholar. Not only do dissertations contain literature reviews, but most articles and grant proposals have some form of literature review included in them. The reason the literature review is so prevalent in scholarly writing is that it functions as an argument about how your project fits in the ongoing scholarly conversation in your field and justifies your project.

A successful literature review does more than list the research that has preceded your work. A literature review is not simply a summary of research. Your literature review must not only demonstrate that you understand important conversations and debates surrounding your project and your position in regard to the conversations, but it must also create an argument as to why your work is relevant to your field of study. In order to create such an argument you must evaluate the relevant research, describing its strengths and weaknesses in relation to your project. You must then explain how your project will build on the work of other researchers, and fill the scholarly gaps left by other researchers. What is typically included in a Literature Review and how do I start?

To show how your project joins an existing scholarly conversation you need to provide readers with the necessary background to understand your research project and persuade them that your intervention in the scholarly conversation is necessary. The first step is to evaluate and analyze the scholarship that is key to understanding your work. The scholarship you evaluate may include previous research on similar topics, theoretical concepts and perspectives, or methodological approaches. Evaluating existing research means more than just summarizing the scholar’s main point. You will also want to assess the strengths and limits of the writer’s project and approach. Questions to consider as you read include: What problems or issues is the writer exploring? What position does the writer take? How is the writer intervening in an ongoing conversation? Where does the writer leave the issue?

Once you have evaluated the research of others, you need to consider how to integrate ideas from other scholars with your ideas and research project. You will also need to show your readers which research is relevant to understanding your project and explain how you position your work in relationship to what has come before your project. In order to do this, it may be helpful to think about the nature of your research project. Not all research has the same purpose. For example, your research project may focus on extending existing research by applying it in a new context. Or you may be questioning the findings of existing research, or you may be pulling together two or more previously unconnected threads of research. Or your project may be bringing a new theoretical lens or interpretation to existing questions. The focus of your research project will determine the kind of material you need to include in your literature review. What are some approaches for organizing a Literature Review? In the first part of a literature review you typically establish several things. You should define or identify your project and briefly point out overall trends in what has been published about the topic – conflicts, gaps in research, foundational research or theory, etc. You should also establish your position – or argument - for the project and the organization of the review.

In the body of the literature review, consider organizing the research and theory according a particular approach. For example, you could discuss the research chronologically. Or you could organize the research thematically, around key ideas or terms or theoretical approaches. Your literature review may include definitions of key terms and the sources from which they are drawn, descriptions of relevant debates in the field, or a description of the most current thinking on your topic.

You will also want to provide clear transitions and strong organizing sentences at the start of sections or paragraphs. You may find it helpful to divide the body of the review up into individual sections with individual subheadings. As you summarize and evaluate studies or articles keep in mind that each article should not necessarily get the same amount of attention. Some scholarship will be more central to your project and will therefore have to be discussed at more length. There also may be some scholarship that you choose not to include, so you might need to explain those decisions. At every turn, you want to keep in mind how you are making the case for how your research will advance the ongoing scholarly conversation. What can the Writing Center do to help? It can sometimes be difficult, after reading pages and pages of research in your field, to step back from the work and decide how best to approach your literature review. Even before you begin to write you may find a consultation in the Writing Center will help you plan out your literature review. Consultants at the Writing Center are experienced in working with scholars to help them reflect on and organize their work in a literature review so it creates the argument for your project. Make an appointment to work with us on your focus and organization even before you begin to write. We are also able to help you by reading and responding to your drafts or to help with issues of documentation. We can help you understand the genre conventions of the literature review, work through revisions, and help you learn how to edit your own work.  We recommend that you come in early to give yourself enough time to work through any problems that may come up as you write.

Literature reviews made easy

Turn that jumble of notes and ideas into a well-organized draft with these five strategies.

By Cassandra Willyard

Print version: page 28

Alarm, terror, worry, despair, panic. Do those words describe how you feel about writing your dissertation? If so, you're not alone. The dreaded doctoral dissertation can inspire fear in even the most courageous students.

After you've selected a topic, one of the first major tasks is writing the literature review — the section some experts say is the most difficult and time-consuming. Unlike the methods and results sections, which follow a highly regimented format, the literature review gives students more latitude to develop their own ideas, says Sharon Foster, PhD, a psychologist at Alliant International University and co-author of "Dissertations And Theses from Start to Finish: Psychology and Related Fields" (1993). "You're not just summarizing what's known," Foster says. "You're also trying to figure out what needs to be known to advance the science."

That means critically evaluating the literature and looking for holes, unanswered questions and methodological weaknesses.

Here are five strategies to keep you focused and productive as you tackle the first section of your dissertation:

Get Organized

To conduct a thorough review of the literature, you'll need to read dozens of papers. Unless you possess supernatural powers of memorization, you'll want to create a system for keeping track of the important information. What kind of system is up to you. "There is no template," says Joan Bolker, EdD, author of "Writing Your Dissertation in Fifteen Minutes a Day: A Guide to Starting, Revising, and Finishing Your Doctoral Thesis" (1998). "You have to look at who you are. You have to figure out what's going to fit for you."

For example, if you're the type of student who makes detailed outlines, keeps immaculate files and thinks organizational software is fun, approach your dissertation with the same organizational gusto that you approach the rest of your life. If you're technologically savvy, use the latest smartphone app to keep track of your notes. But if organization doesn't come naturally, keep your system simple. A complex method of index cards and color-coded tabs may make you feel overwhelmed. Even keeping separate, albeit messy, piles can help tame the chaos. You don't have to be an organizational guru to write a dissertation, Bolker says. "I've had several [students who were] slobs who wrote fantastic dissertations."

Whatever system you choose, keep track of your citations. You don't want to be one of the students "scurrying around the library to look up the references" right before the deadline, Bolker notes.

Stay Focused

Students often cast too wide a net when they start their literature reviews, Foster says. "They think they have to write about everything they've read." The result is a huge literature review with too much background and not enough information about your specific research topic. If your dissertation is on relational aggression among elementary school kids, focus in quickly on the type of aggression you're interested in and the age group rather than writing 20 pages of background on aggression, Foster says.

To help narrow your focus, Foster recommends writing the end of the literature review — the part directly relevant to your research question — first. "Then go back and write your introductory materials," she says.

Set a Schedule

Writing is a creative process, but that doesn't mean you should only work when inspiration strikes, says Kjell Rudestam, PhD, associate dean at Fielding Graduate University and author of "Surviving Your Dissertation: A Comprehensive Guide to Content and Process, 3rd edition" (2007). Instead, set aside time to work on your literature review. How much time? That depends on the requirements of your department and how quickly you work. "Some [departments] prefer a very broad and comprehensive review, whereas others prefer a review that is more publication-ready," Rudestam says. The average review may take six months to write and require multiple revisions. "If you don't schedule some time for the dissertation," he says, "it will slip into the background."

Seek Feedback Early and Often

Don't avoid your dissertation committee. Many students do, Rudestam says, because they're afraid that the committee members will raise questions and create more work for them. But you need that kind of feedback. "Typically, it's the committee members, especially the chair of the committee, who have the most awareness and knowledge about the available literature," he says. So your committee can be a valuable resource if you need help figuring out which topics to cover in your literature review or identifying key studies. A student who gets lots of critical feedback early on is more likely to end up with "a dissertation that's bulletproof," Rudestam says.

Seek advice, but don't be afraid to take only what you need. "Three [committee] members are likely to give three different sorts of advice and drive the writer nuts," Bolker says.

Find Your Voice

One of the biggest challenges students face is "making the work their own," Rudestam says. When students write a first draft of the literature review, they often rely too heavily on the opinions of others. "Smith said this. Jones did this. Schwartz thinks this," he says. "You wonder where the author is." Instead of citing an exhaustive list of articles, identify the argument you want to make and then select only the papers that are relevant — those that either support your argument or dispute your hypothesis.

The process of writing a dissertation's literature review is undoubtedly labor-intensive, but it can also be immensely rewarding. "I've had a lot of students who have started out dreading doing a dissertation," Rudestam says. By the end, however, they regard their dissertation as "the most meaningful thing that they did with their graduate studies."

About Systematic Reviews

How Long Does It Take To Do a Systematic Review?

Automate every stage of your literature review to produce evidence-based research faster and more accurately.

A systematic review is a study of evidence conducted to answer a specific research question. It uses systematic, explicit, and reproducible methods to identify, choose, and appraise existing research based on predetermined criteria. This data is then extracted and analyzed, to be included in the review. A systematic review involves intensive research, and thus requires a lot of legwork; Completing one can take anywhere between six to eighteen months, depending on several factors including the scope of the topic, the size of the research team, and the steps in a systematic review .

What Is A Systematic Review?

A systematic review is a study that answers a focused research question by employing a comprehensive research strategy that identifies, screens, and evaluates all studies, whether published or unpublished, relevant to the topic. Once all the research is assessed based on strict eligibility criteria (i.e. only qualified studies are included, while others are not), it’s presented as an unbiased and balanced summary of the findings.

Many people wonder, “ are systematic reviews qualitative or quantitative ?” The answer is that they could be either. A qualitative systematic review uses observation, interviews, or verbal interactions, deriving data from meanings and interpretations of the data collected from the participants. Meanwhile, a quantitative systematic review works with studies that include numerical data. There also are mixed-type reviews which are a combination of quantitative and qualitative reviews.

Steps in a Systematic Review

A systematic review is one of the most rigorous evidence-gathering processes. It starts learning how to choose a topic for systematic review (which usually involves defining a specific research question that hasn’t been reviewed before. If the systematic review is on a topic that has been reviewed before, it should try to fill the gaps identified by the previous review) and ends with writing the paper.

The following are the steps for conducting a review:

• Defining the research question
• Checking for existing reviews or protocols
• Assembling a team
• Developing and registering a protocol
• Conducting a thorough literature search
• Selecting relevant studies
• Critically appraising selected studies
• Performing data extraction
• Assessing, synthesizing, and analyzing results
• Interpreting findings
• Writing the paper

How Long Does It Take To Do A Systematic Review?

The amount of time it takes to do a systematic review varies. Due to its research-intensive nature, it generally takes between six to eighteen months. This includes going through all the steps in a systematic review previously outlined, as well as the necessary training and meetings required to accomplish the research.

Factors That Affect The Duration Of A Systematic Review

Several factors affect how long it takes to do a systematic review. These include but aren’t limited to

• The topic of the review
• The number of people in the team and their availability, i.e. if the researchers are doing the study full-time or part-time
• Required training
• Research methods i.e. the extent of efforts to obtain relevant literature
• Availability of studies
• Experience of the authors
• Support provided to the team

A systematic review is one of the most research-intensive evidence-gathering processes. It involves several steps and, depending on the various factors involved, can take between six to eighteen months to complete. There are no shortcuts to doing it thoroughly. But there are ways to streamline and simplify the process using literature review software such as DistillerSR which allows researchers to automate every step of a systematic review, from literature search, data extraction to auditing. This helps in securely producing evidence-based research faster and more accurately.

The question "how long does it take to write a literature review?" is one that many students and researchers often ask, and for good reason. A literature review is a crucial part of any research project, academic paper, or doctoral research proposal. Understanding its length and complexity can help in planning and executing the writing process efficiently.

A literature review is a type of academic writing that provides an overview of existing research on a particular topic. It identifies, assesses, and synthesizes scholarly articles, research papers, and other relevant literature to inform the reader about the current state of research on a specific area of study.

The purpose of a literature review is multifaceted. It aims to identify gaps in existing research, provide background information on a research topic, validate the research question, and set the stage for your own research project. It enables researchers to understand the existing landscape of their field of study, thereby guiding their own research methodologies and questions.

The importance of a literature review is paramount in establishing the validity of your research paper or proposal. It helps in framing your research question and showcasing that your study is not a mere repetition, but rather an addition to existing knowledge. By summarizing previous research, it offers a point of view and creates a foundation for new research.

The length of a literature review can vary depending on the depth of the research topic and the guidelines set by a particular institution or journal. In most cases, literature reviews range from 2000 to 5000 words. However, for doctoral dissertations, it can be much more extensive.

1. Narrative Review

2. Systematic Review

3. Meta-analysis

4. Scoping Review

5. State-of-the-Art Review

Writing a literature review can take anywhere from several days to several weeks, depending on the breadth and depth of the subject matter. Researchers need to gather relevant literature, read through them, synthesize key findings, and finally, write the review article while following the appropriate research methodology and citations styles like APA.

A 1000-word literature review can generally be completed within a day or two, assuming that you have already completed the required reading and have a plan for your review. However, this duration can vary depending on the complexity of the topic and the need for extensive research.

While both are academic papers, a literature review summarizes and synthesizes existing research, whereas a research paper presents new research findings. A literature review can be a stand-alone paper or a review section within a larger research paper.

Writing a literature review in 30 minutes or less is unrealistic for most comprehensive reviews. However, you could potentially draft a very rough outline or jot down key points, citations, and topic sentences to be expanded upon later.

What Steps Should Follow to Write an Effective Literature Review?

1. Identify a Research Topic

How much time should I spend on reviewing a paper?

I never tried to avoid becoming a sub-reviewer, and still, this question made me wonder. How much time should I, as a PhD student, spend on a review of a paper that my advisor gave me to do? Does the answer depend on whether I'm getting credit for the review or not, that is whether I'm a sub-reviewer or not?

• peer-review
• working-time

5 Answers 5

You should do slightly more reviewing work for the community than the community does for you. So, as a rough estimate, assuming every paper you write and submit needs three reviews and your average paper has three authors, you should review slightly more papers than you submit.

There is no way to predict in the abstract how long a paper takes to review; that varies from field to field, subfield to subfield, and even paper to paper. Answering a similar question in Theoretical Computer Science Stack Exchange , I wrote:

Expect to spend about an hour per page, mostly on internalizing the paper's results and techniques. Be pleasantly surprised when it doesn't actually take that long. (If it takes significantly less time than that, either the paper is either exceedingly elegant and well-written, you know the area extremely well, or the paper is technically shallow. Don't confuse these three possibilities.)

No, the answer does not depend on whether you get credit for the review. If you're not going to write a thorough, professional review, just say no.

• 9 +1 for not accepting the review if you do not intend to invest the time needed. –  Paul Hiemstra Commented Dec 16, 2012 at 20:58
• 11 Note that you must calculate based on papers submitted and reviewed not papers published. –  Rex Kerr Commented Dec 17, 2012 at 16:28
• I fully agree with this answer. @JeffE –  Coder Commented May 9, 2016 at 14:27
• 1 A very nice answer, except that if your advisor gives you a subreview, most likely you can't "just say no". Your advisor expects a review. –  Caleb Stanford Commented May 29, 2018 at 23:44
• 1 @StrongBad Closer to the former. A quick glance at my own papers suggests that preprints, including conference and journal submissions, typically have about 600-750 words per page; this is probably the most common format that people actually read. Single-column mathy-journal papers have about 500 words per page; two-column proceedings papers can have over 1000 words per page. Nobody double-spaces anything. –  JeffE Commented Dec 21, 2018 at 15:37

Read the entire paper in one go. For a 12 page* paper, that should take you an hour at most. This is the first pass. From this you can now decide how to proceed, now that you have (quickly) covered all the sections. (edit: The goal on this first pass is not to understand all the details, but rather get an overall feeling of the paper, quality and organization of ideas)

If a paper is terribly written and difficult to understand you should reject it outright for being so. It should not take a reader 12 hours to read a 12 page paper - and indeed, many papers are badly written and do take this much time - and you are still left wondering because it was not clear.

If the basic claims seem sound and sufficiently interesting/important and the idea is clear enough to understand, then you need to dig in. Depending on the type of paper this means looking at definitions, proofs, or experimental design, hypothesis testing and the analysis of the results. Likewise for any related work you know of that should be cited (and not just your own - that is too cliche! - if you do recommend your work as a citation at least include some others!).

All along, help people out with typos and readability. As a reviewer, you are the last chance to make this a good read before it is published.

And even if you reject it, don't just shoot people down. Give them ideas about how to make the paper stronger, suggestions for different directions, etc. Remember that it is most likely some other student who will receive your review back - so try and help them make the next paper better.

(* 12 single column pages. A 6 page paper with two columns can often contain the same amount of text as a 12 page single column paper)

• 11 Your answer is somewhat field-oriented. Very few 12-pages papers in my field (fundamental mathematics) can be read in one hour (except if you mostly read the introduction), at least not by me. –  Benoît Kloeckner Commented Dec 17, 2012 at 12:24
• 2 I am also a mathematician, and I agree with Benoit. One can easily (and profitably) spend more than one hour per page on a math paper. On the other hand, there are other 12 page papers that I have spent only a few hours reviewing in total...and have recommended for acceptance. This makes me think that it is not helpful to suggest figures on hours per page. –  Pete L. Clark Commented Dec 17, 2012 at 16:52
• 2 In my field, computer science, and especially papers with theoretical proofs and algorithms, it is the same. I still think that a full first pass of the paper in an hour is a good approach for the following reason: if the paper cannot compel you to dig deeper with a single pass at 1 hour, how do you expect any other reader to actually read this paper. The first pass should entice you into going deeper - if it does not because it is badly written or makes a trivial claim, then it not worth going further. –  Tom Carchrae Commented Dec 17, 2012 at 18:47
• 1 @Tom: sure, taking about an hour to flip through a 12 page paper sounds quite reasonable. I was objecting to your sentence "It should not take a reader 12 hours to read a 12 page paper". Why not?? Or are you still talking about skimming when you say this? –  Pete L. Clark Commented Dec 20, 2012 at 18:52
• I agree with your previous comment - there is no magic number on the number of hours you can spend reading a paper, especially one that is several pages of proof. That said, I still feel that it is an author's obligation to make the salient points clear enough for a reader to understand the big idea quickly! As to the upper bound on time taken to digest the details of a paper, that could take a lifetime. In the case of a review, I would only progress to this level(not a lifetime) of detail if the big idea was clear and significant. –  Tom Carchrae Commented Dec 20, 2012 at 21:41

There is no clearcut answer to how long a review takes. I would say that the amount of time spent on it is the time you need to understand the paper and provide good advice on wether or not it is a paper that can be accepted, with some changes or as is. In general, this should take you around a full working day. How long this exactly becomes depends on:

• The level and clarity of the paper (very bad paper takes less time, mediocre paper takes more time, very good paper takes less time).
• Your familiarity with the subject (less familiar more time).
• The requirements of the journal/conference you are reviewing for, is it a full review, or just a go/no go.

It depends on how many reviews you've done and what your experience is. If you're just starting out and have never reviewed a paper before, you should expect it to take a minimum of several hours to do a decent to good review.

Your mileage may vary depending on what discipline you're in, but a good review generally will consist of:

• a summary of what the contribution of the paper was
• a brief list of 1-3 strengths and 1-3 weaknesses that the paper had
• several paragraphs explaining those strengths and weaknesses in greater detail along with constructive suggestions of what would be needed to improve the weaknesses
• a brief listing of any related work that you feel is missing from the paper
• a recommendation to the reviewing committee of whether or not you believe the paper should be accepted
• usually there is a part for a numerical evaluation of your expertise and whether or not it should be accepted

The more reviews that you do, the less time that you should need to spend on doing the review. It seems like many professors can knock out a review in an hour or less, but most of the graduate students I've seen will tend to spend at least 1-2 hours per review if they're doing a good job.

• 5 Same comment than to Tom Carchrae answer: your time indications must be somehow field oriented, because I cannot see how one would do even a barely decent review in one or two hours in my field (where typical reviews come back six months after submission, due to the time it needs from the referee). –  Benoît Kloeckner Commented Dec 17, 2012 at 12:27
• 5 Why would you limit the review to 1-3 weakness? Surely you want to point out all the weaknesses. –  StrongBad Commented Dec 17, 2012 at 13:10
• Again, your mileage may vary depending on what discipline you're in, but my understanding has always been that you want to try to group weaknesses into a few main points in a list, then to expand on all of the things that are wrong in the paragraphs under the headings of those topics so that it's easier for the authors to understand your criticisms and to address them. –  Zai Commented Dec 17, 2012 at 13:53
• 7 I think it is on the border of irresponsible to suggest that a review of a paper can or should be done in an hour or less. –  Pete L. Clark Commented Dec 17, 2012 at 16:56

Take enough time to find most (~80%) of the important strengths and weaknesses of the paper and to describe and explain the weaknesses thoroughly and clearly but if you encounter one particular non-core aspect or section of the paper that would take excessively long to do this, just skip it and be frank: "I have not reviewed ((aspect X)) thoroughly, because my expertise in this area is too shallow."

If the editor is worth her salt, this will actually increase her confidence in the rest of your review.

All of your reviews should be careful but none of them need to be perfect.

How Long Does It Take to Write a Book? Find Out Now!

• The Speaker Lab
• June 30, 2024

Table of Contents

Dreaming about writing a book is one of the most exciting parts of writing. The writing part? Well, that’s when it gets a little harder. Once you’ve written out the few scenes you had a clear vision for, you inevitably hit writer’s block. Then you can’t help but wonder: how long does it take to write a book anyway? This question is one that haunts every aspiring author. And the truth is, there’s no one-size-fits-all answer. Some churn out novels in months; others take years.

The length of time depends on various factors such as genre, word count, personal writing speed, and life circumstances. You might be juggling this with a full-time job or managing family commitments. But don’t worry! Whether you’re aiming for 50k words or an epic saga over 100k words, we have insights that’ll help you map out your journey.

Factors That Affect How Long It Takes to Write a Book

If you’re wondering how long it takes to write a book, the answer is: it depends. Every author’s writing process is unique, and the time it takes to complete a book can vary greatly. However, several key factors influence the average writing time.

Book Length and Genre

The length and complexity of your book will impact how long it takes to write. Novels and non-fiction books that require extensive research generally take longer than shorter works like novellas or memoirs. For example, a fiction book with an 80,000 word count might take 6-8 months, while a 40,000-word self-help book could be completed in just a few months.

Writing Schedule and Consistency

The book-writing timeline differs from author to author. It depends on how much time you can set aside for writing and how many words you’re able to write during each session. Establishing a consistent writing routine can help you make steady progress and write faster.

Experience Level and Writing Skills

General speculation suggests that first-time authors take about 1-2 years to complete a book. Learning curves and the need for extensive rewriting often stretch out timelines for new writers compared to more experienced authors. As you hone your writing skills and develop a more efficient writing process, you’ll likely be able to write subsequent books faster.

Research and Planning

The time it takes to complete a book is influenced by various factors, including the complexity of the subject matter. Books that require extensive research or world-building, such as historical fiction or fantasy epics, may take significantly longer than projects in other genres. Investing time in thorough planning and outlining can help streamline the actual writing process.

Average Time to Write a Book Based on Word Count

One of the most significant factors influencing how long it takes to write a book is the target word count. While there’s no one-size-fits-all answer, understanding the average writing time for different word counts can help you set realistic expectations for your own book writing process.

50,000 to 80,000 Words

For a typical novel ranging from 50,000 to 80,000 words, the average time to write a complete first draft is around 3-7 months when writing consistently. In other words, you’d have to write between 400-600 words a day to meet this goal. However, many authors take significantly longer to perfect their manuscripts. The ideal word count for your book depends on your genre and target audience.

80,000 to 100,000 Words

Longer novels between 80,000 to 100,000 words, which are common in genres like fantasy, historical fiction, and literary fiction, often take authors 6 months to a year to draft. The increased word count and plot complexity add to the writing time. Keep in mind that the length of your book will impact not only the writing process but also the editing and publishing stages.

Over 100,000 Words

For books exceeding 100,000 words, such as expansive non-fiction works or epic novels, authors may spend a year or longer just on the first draft. Researching, outlining, and revising these lengthy projects can extend the timeline to several years in some cases. It’s essential to break down the writing process into manageable chunks and set achievable milestones to stay motivated throughout the journey.

Writing Speed and Daily Word Count Goals

Your writing speed and daily word count goals play a significant role in determining how long it takes to write your book. By understanding your own writing habits and setting realistic targets, you can establish a sustainable writing process that helps you complete your book in a timely manner.

Slow and Steady Approach

Authors who prefer a slow and steady approach may set a modest daily word count goal of 500-1,000 words. At this pace, writing a complete draft can take several months to a year, but it allows for a more manageable and less stressful writing process. In fact, renowned author Terry Pratchett set his writing goal at 400 words a day, so don’t be discouraged if you aren’t churning out as much as your writer friends. Consistency is key, so aim to write during your most productive hours each day.

Intensive Writing Sprints

Some authors engage in intensive writing sessions , aiming to write a higher volume of words in a short period. This may involve setting aside dedicated weeks or months to focus solely on the book and striving for 2,000-5,000 words per day. While this approach can lead to a faster first draft, it requires significant discipline and may not be sustainable for all writers. Be sure to balance intensive writing sprints with periods of rest and reflection.

Finding Your Ideal Writing Pace

Ultimately, the ideal writing pace varies from author to author. Some may thrive under the pressure of ambitious daily word counts, while others prefer a more relaxed approach. Experimenting with different writing routines and tracking your progress can help you find a sustainable pace that works for you. Remember, the key is to maintain consistency and make steady progress towards your goal of completing your book.

Famous Authors and Their Book Writing Timelines

Crafting a novel involves extensive research, revisions, and fine-tuning sentences, which can significantly extend the writing process. But what about some of the most famous authors in history? How long did it take them to write their masterpieces?

Stephen King

Known for his prolific output, Stephen King has published over 60 novels and more than 200 short stories. While he’s known for his speedy writing, it still takes him several months to complete a novel.

For example, King wrote the first draft of The Shining in just four months, but spent several more months revising and editing. His novel 11/22/63 took him over two years to research and write.

Margaret Mitchell

Margaret Mitchell, author of the classic Gone with the Wind , spent ten years writing her epic novel . She began writing in 1926, but didn’t finish until 1936. Mitchell was a perfectionist and extensively researched the Civil War era to ensure historical accuracy.

William Faulkner

William Faulkner, known for his complex, stream-of-consciousness style, was a relatively fast writer. He wrote As I Lay Dying in just six weeks and The Sound and the Fury in six months. However, he spent years editing and revising his work to achieve his distinctive style.

These famous authors demonstrate that there’s no one “right” timeline for writing a book. Some authors can crank out a draft in a matter of weeks, while others may take years to perfect their prose. The key is finding a writing process that works for you and staying dedicated to your craft.

Tips for Writing Your Book Faster

While writing a book is a time-consuming process, there are strategies you can use to speed things up without sacrificing quality. Below are some tips to help you write your book faster.

Set a Writing Schedule

Establishing a consistent writing schedule is crucial for making steady progress on your book. Block out dedicated writing time in your daily or weekly routine, and treat it as a non-negotiable commitment. Having a set schedule helps you build momentum and keeps your project moving forward.

Break Down Your Writing Goals

Break down your overall book-writing goal into smaller, manageable milestones. Set achievable targets for each writing session , whether it’s a word count or a specific scene or chapter you want to complete. Celebrating these smaller victories can help maintain motivation and keep you from feeling overwhelmed.

Minimize Distractions

Eliminate distractions during your designated writing time to maximize productivity. Find a quiet workspace, turn off notifications on your devices, and resist the urge to check social media or emails. Use tools like website blockers or noise-canceling headphones to create a focused environment conducive to writing.

Embrace Imperfection in Your First Draft

Embrace the idea that your first draft will be imperfect. Avoid getting bogged down in constant self-editing or striving for perfection right away. Instead, focus on getting your ideas down on paper and maintaining forward momentum. You can always revise and refine your work during the editing phase.

Remember, the key to writing your book faster is consistency and dedication. By setting a schedule, breaking down your goals, minimizing distractions, and embracing imperfection, you’ll be well on your way to completing your book in record time.
