Writing Research Papers

• Writing a Literature Review

When writing a research paper on a specific topic, you will often need to include an overview of any prior research that has been conducted on that topic.  For example, if your research paper is describing an experiment on fear conditioning, then you will probably need to provide an overview of prior research on fear conditioning.  That overview is typically known as a literature review.  

Please note that a full-length literature review article may be suitable for fulfilling the requirements for the Psychology B.S. Degree Research Paper .  For further details, please check with your faculty advisor.

Different Types of Literature Reviews

Literature reviews come in many forms.  They can be part of a research paper, for example as part of the Introduction section.  They can be one chapter of a doctoral dissertation.  Literature reviews can also “stand alone” as separate articles by themselves.  For instance, some journals such as Annual Review of Psychology , Psychological Bulletin , and others typically publish full-length review articles.  Similarly, in courses at UCSD, you may be asked to write a research paper that is itself a literature review (such as, with an instructor’s permission, in fulfillment of the B.S. Degree Research Paper requirement). Alternatively, you may be expected to include a literature review as part of a larger research paper (such as part of an Honors Thesis). 

Literature reviews can be written using a variety of different styles.  These may differ in the way prior research is reviewed as well as the way in which the literature review is organized.  Examples of stylistic variations in literature reviews include: 

• Summarization of prior work vs. critical evaluation. In some cases, prior research is simply described and summarized; in other cases, the writer compares, contrasts, and may even critique prior research (for example, discusses their strengths and weaknesses).
• Chronological vs. categorical and other types of organization. In some cases, the literature review begins with the oldest research and advances until it concludes with the latest research.  In other cases, research is discussed by category (such as in groupings of closely related studies) without regard for chronological order.  In yet other cases, research is discussed in terms of opposing views (such as when different research studies or researchers disagree with one another).

Overall, all literature reviews, whether they are written as a part of a larger work or as separate articles unto themselves, have a common feature: they do not present new research; rather, they provide an overview of prior research on a specific topic . 

How to Write a Literature Review

When writing a literature review, it can be helpful to rely on the following steps.  Please note that these procedures are not necessarily only for writing a literature review that becomes part of a larger article; they can also be used for writing a full-length article that is itself a literature review (although such reviews are typically more detailed and exhaustive; for more information please refer to the Further Resources section of this page).

Steps for Writing a Literature Review

1. Identify and define the topic that you will be reviewing.

The topic, which is commonly a research question (or problem) of some kind, needs to be identified and defined as clearly as possible.  You need to have an idea of what you will be reviewing in order to effectively search for references and to write a coherent summary of the research on it.  At this stage it can be helpful to write down a description of the research question, area, or topic that you will be reviewing, as well as to identify any keywords that you will be using to search for relevant research.

2. Conduct a literature search.

Use a range of keywords to search databases such as PsycINFO and any others that may contain relevant articles.  You should focus on peer-reviewed, scholarly articles.  Published books may also be helpful, but keep in mind that peer-reviewed articles are widely considered to be the “gold standard” of scientific research.  Read through titles and abstracts, select and obtain articles (that is, download, copy, or print them out), and save your searches as needed.  For more information about this step, please see the Using Databases and Finding Scholarly References section of this website.

3. Read through the research that you have found and take notes.

Absorb as much information as you can.  Read through the articles and books that you have found, and as you do, take notes.  The notes should include anything that will be helpful in advancing your own thinking about the topic and in helping you write the literature review (such as key points, ideas, or even page numbers that index key information).  Some references may turn out to be more helpful than others; you may notice patterns or striking contrasts between different sources ; and some sources may refer to yet other sources of potential interest.  This is often the most time-consuming part of the review process.  However, it is also where you get to learn about the topic in great detail.  For more details about taking notes, please see the “Reading Sources and Taking Notes” section of the Finding Scholarly References page of this website.

4. Organize your notes and thoughts; create an outline.

At this stage, you are close to writing the review itself.  However, it is often helpful to first reflect on all the reading that you have done.  What patterns stand out?  Do the different sources converge on a consensus?  Or not?  What unresolved questions still remain?  You should look over your notes (it may also be helpful to reorganize them), and as you do, to think about how you will present this research in your literature review.  Are you going to summarize or critically evaluate?  Are you going to use a chronological or other type of organizational structure?  It can also be helpful to create an outline of how your literature review will be structured.

5. Write the literature review itself and edit and revise as needed.

The final stage involves writing.  When writing, keep in mind that literature reviews are generally characterized by a summary style in which prior research is described sufficiently to explain critical findings but does not include a high level of detail (if readers want to learn about all the specific details of a study, then they can look up the references that you cite and read the original articles themselves).  However, the degree of emphasis that is given to individual studies may vary (more or less detail may be warranted depending on how critical or unique a given study was).   After you have written a first draft, you should read it carefully and then edit and revise as needed.  You may need to repeat this process more than once.  It may be helpful to have another person read through your draft(s) and provide feedback.

6. Incorporate the literature review into your research paper draft.

After the literature review is complete, you should incorporate it into your research paper (if you are writing the review as one component of a larger paper).  Depending on the stage at which your paper is at, this may involve merging your literature review into a partially complete Introduction section, writing the rest of the paper around the literature review, or other processes.

Further Tips for Writing a Literature Review

Full-length literature reviews

• Many full-length literature review articles use a three-part structure: Introduction (where the topic is identified and any trends or major problems in the literature are introduced), Body (where the studies that comprise the literature on that topic are discussed), and Discussion or Conclusion (where major patterns and points are discussed and the general state of what is known about the topic is summarized)

Literature reviews as part of a larger paper

• An “express method” of writing a literature review for a research paper is as follows: first, write a one paragraph description of each article that you read. Second, choose how you will order all the paragraphs and combine them in one document.  Third, add transitions between the paragraphs, as well as an introductory and concluding paragraph. 1
• A literature review that is part of a larger research paper typically does not have to be exhaustive. Rather, it should contain most or all of the significant studies about a research topic but not tangential or loosely related ones. 2   Generally, literature reviews should be sufficient for the reader to understand the major issues and key findings about a research topic.  You may however need to confer with your instructor or editor to determine how comprehensive you need to be.

Benefits of Literature Reviews

By summarizing prior research on a topic, literature reviews have multiple benefits.  These include:

• Literature reviews help readers understand what is known about a topic without having to find and read through multiple sources.
• Literature reviews help “set the stage” for later reading about new research on a given topic (such as if they are placed in the Introduction of a larger research paper). In other words, they provide helpful background and context.
• Literature reviews can also help the writer learn about a given topic while in the process of preparing the review itself. In the act of research and writing the literature review, the writer gains expertise on the topic .

Psychology - How to Write a Literature Review

Subject guide.

What is a literature review? 

A literature review discusses published research studies on a specific topic or subject area.  

What is the purpose of writing it?

The goal of the lit review is to describe, summarize, and evaluate previous research in a given area.  It should explain important conclusions about your topic as well as identify any gaps in the research or areas for future study.

Choose a Topic and Find Articles

Choose a topic that interests you and remember to keep an open mind.  Depending on how much research there is, you may need to narrow or broaden your topic.  

• PsycArticles This link opens in a new window Scholarly journal articles on psychology topics.
• ProQuest Central This link opens in a new window The largest single periodical resource available, bringing together complete databases across all major subject areas, including Business, Health and Medical, Social Sciences, Education, Science and Technology, and Humanities.
• Google Scholar Search for scholarly articles and books. Be aware that the full text may not always be available.

Read the Articles

You want to read and understand each of your articles.  A good starting point is to answer these 3 questions about each article:

1. What was the study's research question?  In other words, what were they trying to find out?

2. What was the study's method?  Briefly describe HOW they collected data and WHO their participant group was.

3. What do the results mean?  Or what conclusions can we draw from the results?

Write the Lit Review

Connect:   Think about what YOUR research question is for your lit review.  Each article you found should connect to your topic/theme in some way and you should be able to describe your topic as a research question and your articles as answers to that question.  Your summary for each article should show how they further our knowledge in relation to your topic.

Organize:   Can you organize your articles into a few distinct groups?  It could be by treatment method or age/ethnic group or other factor.  The way you organize will depend on your topic and the research, but it will help you if you can group articles in some way.  

Analyze:  Think beyond just summary and about what we still don't know about this topic.  Are there gaps in the research?  Do too many studies use just one method of gathering data?  What else is important to know?  The "Discussion" section of your articles may help guide you in your analysis.

Literature reviews survey research on a particular area or topic in psychology. Their main purpose is to knit together theories and results from multiple studies to give an overview of a field of research.

How is a Literature Review Different from a Research Article?

Research articles:

• are empirical articles that describe one or several related studies on a specific, quantitative, testable research question
• are typically organized into four text sections: Introduction, Methods, Results, Discussion

The Introduction of a research article includes a condensed literature review. Its purpose is to describe what is known about the area of study, with the goal of giving the context and rationale for the study itself. Published literature reviews are called review articles. Review articles emphasize interpretation. By surveying the key studies done in a certain research area, a review article interprets how each line of research supports or fails to support a theory. Unlike a research article, which is quite specific, a review article tells a more general story of an area of research by describing, comparing, and evaluating the key theories and main evidence in that area.

The Two Purposes of a Literature Review

Your review has two purposes:

(1) to describe and compare studies in a specific area of research and

(2) to evaluate those studies. Both purposes are vital: a thorough summary and comparison of the current research is necessary before you can build a strong evaluative argument about the theories tested.

Getting Started

(1) Select a research topic and identify relevant articles.

(2) Read the articles until you understand what about them is relevant to your review.

(3) Digest the articles: Understand the main points well enough to talk about them.

(4) Write the review, keeping in mind your two purposes: to describe and compare, and to evaluate.

SELECT A TOPIC AND COLLECT ARTICLES

Choose a current, well-studied, specific topic.

Pick a topic that interests you. If you're interested in a subject, you're likely to already know something about it. Your interest will help you to choose meaningful articles, making your paper more fun both to write and to read. The topic should be both current and well studied. Your goal is to describe and evaluate recent findings in a specific area of research, so pick a topic that you find in current research journals. Find an area that is well defined and well studied, meaning that several research groups are studying the topic and have approached it from different perspectives. If all the articles you find are from the same research group (i.e., the same authors), broaden your topic or use more general search terms.

You may need to narrow your topic. The subject of a short literature review must be specific enough, yet have sufficient literature on the subject, for you to cover it in depth. A broad topic will yield thousands of articles, which is impossible to survey meaningfully. If you are drowning in articles, or each article you find seems to be about a completely different aspect of the subject, narrow your topic. Choose one article that interests to you and focus on the specific question investigated. For example, a search for ‘teenage alcohol use’ will flood you with articles, but searching for ‘teenage alcohol use and criminal behavior’ will yield both fewer and more focused articles.

You may need to broaden your topic. You need enough articles on your topic for a thorough review of the research. If you’re unable to find much literature on your topic, or if you find articles you want that are not easy to find online, broaden your topic. What’s a more general way to ask your question of interest? For example, if you’re having a hard time finding articles on ‘discrimination against Asian-American women in STEM fields,’ broaden your topic (e.g., ‘academic discrimination against Asian-American women’ or ‘discrimination against women in STEM.’)

Consider several topics, and keep an open mind. Don't fall in love with a topic before you find how much research has been done in that area. By exploring different topics, you may discover something that is newly exciting to you!

Search the Research Literature

Do a preliminary search. Use online databases to search the research literature. If you don’t know how to search online databases, ask your instructor or reference librarian. Reference librarians are invaluable!

Search for helpful articles. Find one or more pivotal articles that can be a foundation for your paper. A pivotal article may be exceptionally well written, contain particularly valuable citations, or clarify relationships between different but related lines of research. Two sources of such articles in psychology are:

• Psychological Bulletin •
• Current Directions in Psychological Science (published by the American Psychological Society) has general, short articles written by scientists who have published a lot in their research area

How many articles? Although published review articles may cite more than 100 articles, literature reviews for courses are often shorter because they present only highlights of a research area and are not exhaustive. A short literature review may survey 7-12 research articles and be about 10-15 pages long. For course paper guidelines, ask your instructor.

Choose representative articles, not just the first ones you find. This consideration is more important than the length of your review.

Choose readable articles. Some research areas are harder to understand than others. Scan articles in the topic areas you are considering to decide on the readability of the research in those areas.

READ THE ARTICLES

To write an effective review, you’ll need a solid grasp of the relevant research. Begin by reading the article you find easiest. Read, re-read, and mentally digest it until you have a conversational understanding of the paper. You don’t know what you know until you can talk about it. And if you can’t talk about it, you won’t be able to write about it.

Read selectively. Don't start by reading the articles from beginning to end. First, read just the Abstract to get an overview of the study.

Scan the article to identify the answers to these “Why-What-What-What” questions:

• Why did they do the study? Why does it matter?
• What did they do?
• What did they find?
• What does it mean?

The previous four questions correspond to these parts of a research article:

• Introduction: the research question and hypotheses

Create a summary sheet of each article’s key points. This will help you to integrate each article into your paper.

TIP: Give Scholarcy a try.

Read for depth. After you understand an article’s main points, read each section in detail for to gain the necessary indepth understanding to compare the work of different researchers.

WRITE THE LITERATURE REVIEW

Your goal is to evaluate a body of literature; i.e., to “identify relations, contradictions, gaps, and inconsistencies” and “suggest next steps to solve the research problem” (APA Publication Manual 2010, p. 10). Begin writing when you have decided on your story and how to organize your research to support that story.

Organization

Organize the literature review to highlight the theme that you want to emphasize – the story that you want to tell. Literature reviews tend to be organized something like this:

Introduction:

• Introduce the research topic (what it is, why does it matter)
• Frame the story: narrow the research topic to the studies you will discuss
• Briefly outline how you have organized the review
• Headings. Use theme headings to organize your argument (see below)
• Describe the relevant parts of each study and explain why it is relevant to the subtopic at hand.
• Compare the studies if need be, to discuss their implications (i.e., your interpretation of what the studies show and whether there are important differences or similarities)
• Evaluate the importance of each study or group of studies, as well as the implications for the subtopic, and where research should go from here (on the level of the subtopic)

Conclusion: Final evaluation, summation and conclusion

Headings. Use headings to identify major sections that show the organization of the paper. (Headings also help you to identify organizational problems while you’re writing.) Avoid the standard headings of research articles (Introduction, Method, Results, Discussion). Use specific, conceptual headings. If you are reviewing whether facial expressions are universally understood, headings might include Studies in Western Cultures and Studies in Non-Western Cultures. Organize your argument into topics that fit under each heading (one or more per heading).

Describe. For each section or subtopic, briefly describe each article or line of research. Avoid sudden jumps betewen broader and narrower ideas. Keep your story in mind to help keep your thoughts connected.

Compare. For each section or topic, compare related studies, if this is relevant to your story. Comparisons may involve the research question, hypotheses, methods, data analysis, results, or conclusions. However, you don’t want to compare everything. That wouldn’t be a story! Which parts are relevant? What evidence supports your arguments? Identifying strengths and weaknesses of each study will help you make meaningful comparisons.

If you're having trouble synthesizing information, you probably don't understand the articles well. Reread sections you don’t understand. Discuss the studies with someone: you don’t know what you know until you can talk about it.

Evaluate. Descriptions/comparisons alone are not illuminating. For each section or topic, evaluate the studies you have reviewed based on your comparisons. Tell your reader what you conclude, and why. Evaluating research is the most subjective part of your paper. Even so, always support your claims with evidence. Evaluation requires much thought and takes on some risk, but without it, your paper is just a book report.

Final evaluation and summation. On a broader scale, relating to your main theme, tell your reader what you conclude and why. Reiterate your main claims and outline the evidence that supports them.

Conclusion. How does your evaluatio change or add to current knowledge in the field field? What future studies are implied by your analysis? How would such studies add to current knowledge of the topic?

The purpose of a literature review is to survey, describe, compare, and evaluate research articles on a particular topic. Choose a current topic that is neither too broad nor too narrow. Find the story that you want to tell. Spend a lot of time reading and thinking before you write. Think critically about the main hypotheses, findings, and arguments in a line of research. Identify areas of agreement among different articles as well as their differences and areas for future study. Expect to revise your review many times to refine your story. A well-written literature review gives the reader a comprehensive understanding of the main findings and remaining questions brought about by research on that topic.

What is a Literature Review?

Description.

A literature review, also called a review article or review of literature, surveys the existing research on a topic. The term "literature" in this context refers to published research or scholarship in a particular discipline, rather than "fiction" (like American Literature) or an individual work of literature. In general, literature reviews are most common in the sciences and social sciences.

Literature reviews may be written as standalone works, or as part of a scholarly article or research paper. In either case, the purpose of the review is to summarize and synthesize the key scholarly work that has already been done on the topic at hand. The literature review may also include some analysis and interpretation. A literature review is  not  a summary of every piece of scholarly research on a topic.

Why are literature reviews useful?

Literature reviews can be very helpful for newer researchers or those unfamiliar with a field by synthesizing the existing research on a given topic, providing the reader with connections and relationships among previous scholarship. Reviews can also be useful to veteran researchers by identifying potentials gaps in the research or steering future research questions toward unexplored areas. If a literature review is part of a scholarly article, it should include an explanation of how the current article adds to the conversation. (From: https://researchguides.drake.edu/englit/criticism)

Steps for Writing a Literature Review

1. Identify and define the topic that you will be reviewing.

The topic, which is commonly a research question (or problem) of some kind, needs to be identified and defined as clearly as possible.  You need to have an idea of what you will be reviewing in order to effectively search for references and to write a coherent summary of the research on it.  At this stage it can be helpful to write down a description of the research question, area, or topic that you will be reviewing, as well as to identify any keywords that you will be using to search for relevant research.

2. Conduct a Literature Search

Use a range of keywords to search databases such as PsycINFO and any others that may contain relevant articles.  You should focus on peer-reviewed, scholarly articles . In SuperSearch and most databases, you may find it helpful to select the Advanced Search mode and include "literature review" or "review of the literature" in addition to your other search terms.  Published books may also be helpful, but keep in mind that peer-reviewed articles are widely considered to be the “gold standard” of scientific research.  Read through titles and abstracts, select and obtain articles (that is, download, copy, or print them out), and save your searches as needed. Most of the databases you will need are linked to from the Cowles Library Psychology Research guide .

3. Read through the research that you have found and take notes.

Absorb as much information as you can.  Read through the articles and books that you have found, and as you do, take notes.  The notes should include anything that will be helpful in advancing your own thinking about the topic and in helping you write the literature review (such as key points, ideas, or even page numbers that index key information).  Some references may turn out to be more helpful than others; you may notice patterns or striking contrasts between different sources; and some sources may refer to yet other sources of potential interest.  This is often the most time-consuming part of the review process.  However, it is also where you get to learn about the topic in great detail. You may want to use a Citation Manager to help you keep track of the citations you have found. 

4. Organize your notes and thoughts; create an outline.

At this stage, you are close to writing the review itself.  However, it is often helpful to first reflect on all the reading that you have done.  What patterns stand out?  Do the different sources converge on a consensus?  Or not?  What unresolved questions still remain?  You should look over your notes (it may also be helpful to reorganize them), and as you do, to think about how you will present this research in your literature review.  Are you going to summarize or critically evaluate?  Are you going to use a chronological or other type of organizational structure?  It can also be helpful to create an outline of how your literature review will be structured.

5. Write the literature review itself and edit and revise as needed.

The final stage involves writing.  When writing, keep in mind that literature reviews are generally characterized by a  summary style  in which prior research is described sufficiently to explain critical findings but does not include a high level of detail (if readers want to learn about all the specific details of a study, then they can look up the references that you cite and read the original articles themselves).  However, the degree of emphasis that is given to individual studies may vary (more or less detail may be warranted depending on how critical or unique a given study was).   After you have written a first draft, you should read it carefully and then edit and revise as needed.  You may need to repeat this process more than once.  It may be helpful to have another person read through your draft(s) and provide feedback.

6. Incorporate the literature review into your research paper draft. (note: this step is only if you are using the literature review to write a research paper. Many times the literature review is an end unto itself).

After the literature review is complete, you should incorporate it into your research paper (if you are writing the review as one component of a larger paper).  Depending on the stage at which your paper is at, this may involve merging your literature review into a partially complete Introduction section, writing the rest of the paper around the literature review, or other processes.

The APA definition of a literature review (from http://www.apa.org/databases/training/method-values.html ):

 Survey of previously published literature on a particular topic to define and clarify a particular problem; summarize previous investigations; and to identify relations, contradictions, gaps, and inconsistencies in the literature, and suggest the next step in solving the problem.

 Literature Reviews should:

• Key concepts that are being researched
• The areas that are ripe for more research—where the gaps and inconsistencies in the literature are
• A critical analysis of research that has been previously conducted
• Will include primary and secondary research
• Be selective—you’ll review many sources, so pick the most important parts of the articles/books.
• Introduction: Provides an overview of your topic, including the major problems and issues that have been studied.
• Discussion of Methodologies:   If there are different types of studies conducted, identifying what types of studies have been conducted is often provided.
• Identification and Discussion of Studies: Provide overview of major studies conducted, and if there have been follow-up studies, identify whether this has supported or disproved results from prior studies.
• Identification of Themes in Literature: If there has been different themes in the literature, these are also discussed in literature reviews.   For example, if you were writing a review of treatment of OCD, cognitive-behavioral therapy and drug therapy would be themes to discuss.
• Conclusion/Discussion—Summarize what you’ve found in your review of literature, and identify areas in need of further research or gaps in the literature.

Because literature reviews are a major part of research in psychology, Psycinfo allows you to easily limit to literature reviews.  In the advanced search screen, you can select "literature review" as the methodology.

Now all you'll need to do is enter your search terms, and your results should show you many literature reviews conducted by professionals on your topic.

When you find an literature review article that is relevant to your topic, you should look at who the authors cite and who is citing the author, so that you can begin to use their research to help you locate sources and conduct your own literature review.  The best way to do that is to use the "Cited References" and "Times Cited" links in Psycinfo, which is pictured below.

This article on procrastination has 423 references, and 48 other articles in psycinfo are citing this literature review.  And, the citations are either available in full text or to request through ILL.  Check out  the article "The Nature of Procrastination" to see how these features work.

By searching for existing literature reviews, and then using the references of those literature reviews to begin your own literature search, you can efficiently gather the best research on a topic.  You'll want to keep in mind that you'll need to summarize and analyze the articles you read, and won't be able to use every single article you choose.

You can use the search box below to get started.

Adelphi Library's tutorial, Conducting a Literature Review in Education and the Behavioral Sciences covers how to gather sources from library databases for your literature review.

The Literature Review

A literature review is:

1) A list of books and journal articles,

2) on a specific topic,

3) grouped by theme,

4) and evaluated with regard to your research. This evaluation would identify connections, contradictions and gaps in the literature you have found.

The purpose of a literature review, therefore, is:

1) To get a feel for the agreed academic opinion on the subject (the connections).

2) To discover the disagreements on the subject (the contradictions).

3) To find opportunities, (the gaps), for developing and expressing your own opinions.

The classic pattern of academic arguments is

THESIS, ANTITHESIS, SYNTHESIS

An Idea (Thesis) is proposed, an opposing Idea (Antithesis) is proposed, and a revised Idea incorporating (Synthesis) the opposing Idea is arrived at. This revised idea sometimes sparks another opposing idea, another synthesis, and so on…

If you can show this pattern at work in your literature review, and, above all, if you can suggest a new synthesis of two opposing views, or demolish one of the opposing views, then you are almost certainly on the right track.

Steps in compiling a literature review are:

1) Select a specific topic (the more focussed, the better, or you’ll go on for ever).

2) Collect the most relevant (usually "peer reviewed") books and articles.

3) Read/skim them, using the abstract (a short summary attached to the article).

4) Group the articles into the sub-themes of your topic.

5) Identify within each sub-theme those points on which the articles agree, those points on which they disagree, and those points which they don’t cover at all.

1) Choosing your topic

Seek advice from a lecturer or tutor on this, if a topic is not already assigned. It is very common for students to bite off more than they can chew, simply because they have not realised the full breadth and complexity of an apparently simple topic. It is better to cover a tiny topic perfectly, than a huge topic superficially.

Look for a topic on which there is polarised opinion. It often helps to pick one in which a question is being asked, for example: Is a particular taxation policy beneficial or disadvantageous to a developing country?

When authors disagree, this provides an opportunity for you to enter the debate and argue for one side or another in your essay. Taking a hatchet to someone’s opinions (a) gives you something to write about, (b) is fun, (c) is the foundation of much modern scholarly writing.

2) Collect the most relevant (usually "peer reviewed") articles and books

The three tools for finding these books and articles are, in this order:

(a) the relevant section of a good subject encyclopedia, which usually describes the development of the discourse on that subject, gives you an overview of the territory, and ends with a bibliography of the key works on that field. 

(b) the library catalogue and

(c) the library databases of electronic journal articles.

Before you search them, spend a minute thinking about the best terms to use. Make a list of alternative words that describe your subject, and also think about general terms and more specific terms. This is important because the journal databases are good for finding very specific terms in articles, but the library catalogue tends to use more general terms.

To access the library catalogue go to www.lib.uct.ac.za and click on "Catalogue".

If you find a good book reference, scroll down to the bottom of the reference and you will find the subject terms the library cataloguers have assigned to it. Click on that term to call up more books just like the one you have found.

A quick way to check the relevance of any books you find is to glance at the table of contents, the introduction and any descriptive blurbs on the back cover. The index at the back of the book not only helps you dive to very narrow topics in the book, but also gives you an indication of how much attention (i.e. how many pages) the book spends on that specific topic.

If you are satisfied with the book, look at the bibliography in the back – this can help identify other relevant sources. Following a chain of references in a bibliography like this, whether in a book or a journal article, is one of the most basic techniques of scholarship – find something that is relevant and look at the sources it used.

The library’s journal databases are particularly helpful for literature reviews. Journal articles are short and cover very specific topics, so they are more digestible than books and more likely to deal exactly with your topic. They are also quicker to publish than books and so are more likely to be up to date.

To find journal articles by subject go to the library home page at www.lib.uct.ac.za and select "Databases."

Many of these databases allow you to restrict your search to "Peer Reviewed" journals only – these are the most scholarly journals, for which each article has to be vetted by other academics before it is accepted.

Many of our databases are Full Text – so you can usually get the whole article on your desktop for downloading, e-mailing or printing – you don’t have to find it in print on the shelves.

While you can search the Research Portal, or individual journal databases, as simply as you search Google, you can also type in very precise searches by using And, Or, Not operators, Wildcards and Logical Brackets.

An example of such a search would be:

Information Technology AND Brain Drain AND (Employ* OR Jobs OR Labo?r) NOT United States

The AND operator narrows a search – all listed elements must be mentioned in each article: in this example we want articles that cover both Information Technology AND the Brain Drain.

The OR operator expands a search – any of the listed elements must be mentioned in each article: in this example we wanted Information Technology Brain Drain articles that discussed either Employment or Jobs or Labour. The OR operator is useful for dealing with alternative terms which different authors might use when writing on a similar topic.

The Brackets tie the options to the required material. In this example they make sure that any articles we get on labour or employment are concerned with Information Technology and the Brain Drain. If we didn’t have brackets here the search would just bring up every reference to labour in the database, whether relevant to Information Technology or not.

The Wildcards, * and ?, expand a search: The * deals with related words. In this example Employ* means that we get all words starting with "Employ…" – such as Employment, Employee, Employees, Employers…

The ? fills in a missing letter, and is used for covering alternative spellings in British and American English, both Labour and Labor in this example.

NOT weeds out anything you’ve got too much of. Many of our databases are American products, for example, and you can often be flooded with reports on the American situation unless you weed it out.

3) Read/Skim the articles, using their abstracts

Most of the articles will have an abstract. This is a short paragraph at the head of the article that lists the main facts and arguments in each article. By reading these you will quickly get the gist of what each article is about and where it fits into the pattern you are building up in your literature survey.

How many books and articles should you have? It’s wise to check this with your lecturer or tutor. In general, though, your aim is not to cover every single book or article, but every major opinion or theme on the topic. Many of the books or articles will add very little that is new.

Therefore a short list of really scholarly, relevant, comprehensive articles is often more effective than a list of hundreds of superficial or tangential articles.

What you are ideally looking for are the "seminal" articles (seed articles) on which most of the other authors are basing their work.

4) Group the Articles into the themes and sub-themes of your topic

Obviously, it helps to have a structure in mind already, but the articles you find will often help to suggest a structure or cause you to redesign your existing one.

Herewith a hard-learned tip:

There are tides and seasons in academic publishing – a topic is often hot for a few months, then dies, then is revived to be attacked from a different angle, then dies, then is revived again to be discussed from a third angle… remember, Thesis, Antithesis and Synthesis?

This has two implications for studying the results on a database search:

Just because there is nothing much in the recent articles does not mean that it was not hot a few months or years ago, so scroll back in time down the list, or jump right to the earliest reference and scroll up through time to look for a hot spot.

The tides of article titles often tell a story that can help you shape your literature review.

For example, in a list of journal articles on Information Technology and Employment you might find that:

The earliest articles are all about how hard it is to find skilled IT workers.

Later you get articles about UK and US firms desperately recruiting school-leavers and training them in IT skills on the job.

A year later you get articles about how countries like India and South Africa are doing the same thing.

And not long after that you get articles about India and South Africa having a huge, skilled IT workforce, working far more cheaply than the US and UK workforce, and lots of UK and US projects being outsourced to them.

Then you get complaints about unemployment in the IT sector in the UK and USA.

Then you get stories about how employers in the UK and USA have become very choosy about whom they employ, insisting on really good academic training, loads of experience and very-specialised skills.

Then you get the latest stories which are all about how new IT entrants, without that experience, start packing their bags to gain experience elsewhere…

See? Story!

Many database lists of academic articles tell this sort of story when they are looked at in date order. Either they reflect swings in world events or they are reflecting swings in academic debate and opinion. Seeing such a story in the literature is a great help in structuring any literature review.

In particular, look out for the major triggers of such changes: When did the first swing to a new track happen, and what event or article provoked it?

When you find an article that has provoked a major swing, or started a whole new debate, then you are looking at the "Seminal" (Seed) article that I mentioned earlier. This sort of article is often the best sort of article to identify in a literature review – many of the other articles will just build on, comment on, or attack its basic arguments.

Using a Citation Database

If you find a seed article, or any other really good article, we have a magic database, called the ISI Citation Database, which can find all the other articles which have cited that article, either because they support it or because they disagree with it.

The ISI Citation Database is on our database list under ISI WEB OF SCIENCE. There are three versions of it, covering the Sciences, Social Sciences, and Arts and Humanities. You can search all three at once.

Go to "Cited Ref Search" and type in the author’s last name, the journal in which his article appeared and the year it appeared in the appropriate boxes. This will bring up the authors and articles that have followed or disagreed with that author.

Unfortunately this database is not full text, but you can often get the full text of the articles off one or other of our alternative databases.

It is also worth bearing in mind that the PsycInfo database, the main database for Psychology, has a Citation Searching component, which does this job for books and articles on the PsycInfo database.

Another way of doing a citation search is to download Harzing's Publish or Perish software from http://www.harzing.com/pop.htm . This does a lovely job of tracing citations on Google Scholar.

6) Identify within each sub-theme those points on which the articles agree, those points on which they disagree, and those points which they don’t cover at all.

The abstracts can help with this, of course. The main trick is coming up with, or spotting, the sub themes and that is simply a matter of brain work. But if it is done well, and you have taken the trouble to find good sources, then you will find, quite magically, that you have constructed the skeleton and a good bit of the flesh and blood of your essay or research project.

In fact, a good literature review can result in an essay that virtually writes itself.

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.

Copyright ©1995-2018 by The Writing Lab & The OWL at Purdue and Purdue University. All rights reserved. This material may not be published, reproduced, broadcast, rewritten, or redistributed without permission. Use of this site constitutes acceptance of our terms and conditions of fair use.

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.

• A literature review is a critical, analytical summary and synthesis of the current knowledge of a topic. As a researcher, you collect the available literature on a topic, and then select the literature that is most relevant for your purpose. Your written literature review summarizes and analyses the themes, topics, methods, and results of that literature in order to inform the reader about the history and current status of research on that topic.

What purpose does a literature review serve?

• The literature review informs the reader of the researcher's knowledge of the relevant research already conducted on the topic under discussion, and places the author's current study in context of previous studies.
• As part of a senior project, the literature review points out the current issues and questions concerning a topic. By relating the your research to a knowledge gap in the existing literature, you should demonstrate how his or her proposed research will contribute to expanding knowledge in that field.

Systematic Reviews: Introduction

• What is a systematic review?
• How does it differ from a systematic literature review?

A systematic review is a review of research literature (often limited to randomised controlled trials) that is searched for in a systematic or exact manner, and only includes studies that have met strict inclusion criteria. The methodology of the review often follows a internationally recognized systematic review standard or guideline. 

PRISMA definition

"A systematic review is a review of a clearly formulated question that uses systematic and explicit methods to identify, select, and critically appraise relevant research, and to collect and analyze data from the studies that are included in the review." (PRISMA, 2015)

A systematic literature search is a literature review which demonstrates that you have compiled a list of appropriate search terms and includes the structure of your search history, which provides the evidence on which your assignment is based.  You may be told that you need to conduct a systematic review when in fact you just need to perform a literature search in a systematic manner. 

This is a less rigorous process than a systematic review. A systematic review usually covers a wider scope; you would be expected to look at all the available research in the area in question, systematically searching multiple academic databases.

If you are unsure about the differences between a systematic review and a literature review take a look at this guide:  What’s in a Name? The difference between a Systematic Review and a Literature Review and Why it Matters .

Systematic reviews: your research question

Your research question

• Inclusion and exclusion criteria
• PICO framework
• PICO: example

Where possible, select a research topic that you have some basic knowledge in, or are familiar with in.  If this is not possible, seek guidance from your supervisor on the most relevant terminology for your chosen topic.  This will make it easier to devise your research question, ensuring you are using the most appropriate and relevant phrasing.This is especially important when you come to build your search strategy, as the wording of your research question research question will frame your initial search. 

The search terms, phrases, words and subject headings you use in your systematic search play a vital role in your systematic review, because they determine the number and range of results you will get from each database. I f your question is too wide-reaching so will your search, and you will be overwhelmed with  an unmanageable number of search results. You also have to think very carefully about the limitations of your search - such as whether or not you will have a specific date range or limit to a particular study design.  Remember, the clue is in the name - be  systematic  in your approach. 

Inclusion and exclusion criteria 

Before you start to build your search strategy you will need to decide on your review's inclusion and exclusion criteria. This will have a bearing on your search strategy, and potentially determine which studies your systematic search captures. Systematic reviews are measured against a set of specific criteria outlined at the start.  Your inclusion and exclusion criteria dictates which studies will be included in your systematic review (they meet all aspects of your inclusion criteria) and those that will be excluded (does not match your inclusion criteria fully, or meets the exclusion criteria).  You need to think very carefully about the limitations of your research - will you limit to a specific date range or to a particular study design for example.  Remember, the clue is in the name - be  systematic  in your approach. 

Research question:

"For UK children under 5 years of age with a suspected diagnosis of ADHD, what are the recommended clinical assessments used for diagnosis?" 

Inclusion criteria:

• children 0-5 years old 
• suspected ADHD
• limited to clinical assessments specifically, for diagnosis
• UK population studies only

Exclusion criteria:

• any member of the population over the age of 5 
• animal studies
• pre-determined diagnosis of ADHD 
• assessments not defined as "clinical" 
• studies of populations outside of the UK

PICO Framework

In order to structure your search strategy  it can be helpful to use a structured framework.They are designed to help you formulate your research question, search strategy, and inclusion and exclusion criteria. The PICO framework is a popular framework for physiological and health sciences systematic reviews.

PICO stands for:

Population / Patient

Intervention 

You do not have to structure your research to fit into all of the above - it is not prescriptive, but merely a framework to guide you in building your search strategy. Your research question may not have a defined comparative intervention, for example, so you may only use PIO for your framework. 

PICO example

Research question: What impact does Cognitive Behavioural Therapy (CBT) versus pharmaceutical therapy have as treatments for diagnosed anxiety in children  in reducing their anxiety?

Systematic Reviews: the search

• Sample strategy

Your search strategy - where to start

The search terms, phrases, words and subject headings you use in your search play a vital role in your systematic review, because they determine the number and range of results you will get from each database. 

Start with your research question to pick out the  keywords  you will use as the basis of your search. A common practice in systematic review searches is to refer back to the framework you used to structure your research question, such as the PICO framework . This framework gives a clear picture of not only the terms you want to use in your search, but also how you will combine or connect them together in the database.

Using PICO framework for your search 

Research question: Is Cognitive Behavioural Therapy (CBT) more effective than pharmaceutical therapy as a treatment for diagnosed anxiety in teenagers aged 13-18 in managing symptoms of anxiety?

Framework  

Search terms identified: 

• teen/teenager
• 13-18 year olds
• anxiety 
• CBT/cognitive behavioural the rapy
• pharmaceutical/medication
• Improved   management of symptoms

Where to search - Databases

We have grouped the key databases and online resources for psychology in the Key Resources tab . Your dissertation supervisor may also suggest or advise you on the various databases suitable to your search. Some of the most commonly searched databases include: PsycINFO, Web of Science, Cochrane, Scopus, and PubMed. The links for these can be found in the Key Resources tab. 

Where to search - Grey Literature

Depending on your research, you may also need to search grey literature sources in addition to academic database collections. Have a look at the grey literature tab  on the left hand side more information about what defines grey literature and the sources you can search. 

Search techniques 

Consider your keywords carefully 

It's often helpful to look at the abstracts and reference lists of studies or papers you have already engaged with on your topic for a sense of what terminology and specific words/phrases are most common. 

Once you have made a comprehensive list of all the keywords you want to include in your search you need to combine them using what are known as Boolean operators or search connectors. 

Boolean search operators 

In order to combine multiple facets of your search together in a database you will need to use the search operators: AND, OR, NOT. Using operators is common in systematic reviews, and improves the efficiency of your search resulting in more relevant results. Watch the Boolean searching videos to learn more about how to use operators.

Proximity operators 

Using proximity operators in your search allows you to  search for two or more words that occur within a certain number of words from each other. Proximity operators can be helpful when you don't want to limit yourself to searching an exact phrase, for example "diagnosed anxiety", but where you still want to refine your search to a degree. Each database will have its own method of proximity searching, but generally your search looks something like: diagnosed NEAR/3 anxiety - NEAR signifying near to, and 3 signifying the number of words that can appear between "diagnosed" and "anxiety". To ensure proximity searching is available in the database you are searching, have a look for their "search tips" or "search help" page. 

PRESS (Peer Review of Electronic Search Strategies)

The PRESS checklist is a comprehensive evidence-based checklist that does just that. It covers six key aspects of search strategies: 

• the translation of the research question into a search strategy
• the use of any Boolean or proximity operators
• the keywords used 
• spelling, syntax, and commands
• database filters / limits intended for use
• database Subject headings intended for use not essential, and may not apply to your strategy)

Each aspect above has a set of questions to check against your search strategy. The full checklist can be downloaded here . 

Research question

Is Cognitive Behavioural Therapy (CBT) more effective than pharmaceutical therapy as a treatment for diagnosed anxiety in teenagers aged 13-18 in managing symptoms of anxiety?

Step 1: Framework

Step 2: Identify search terms

Step 3: Build search strategy with Boolean operators / commands / proximity operators

Systematic Reviews: guidelines and protocols

• Standards and guidelines
• Cochrane handbook
• Choosing a standard/guideline

Standards and guidelines 

These can serve as guidelines for the structure of your review, from what headings/sections to include, (such as methods, search strategy, etc) to best practice protocols for search strategies, reporting, etc. 

​ The School of Psychology recommends its students follow the PRISMA reporting guidance when conducting a systematic review. 

PRISMA standards

PRISM A  (Preferred Reporting Items for Systematic Reviews and  Meta-Analyses )  is an evidence-based protocol for reporting on systematic reviews and meta-analyses. The School of Psychology recommends its students follow the PRISMA reporting guidance when conducting a systematic review. The PRISMA checklist makes this easy, providing a checklist of criteria to be adhered to for each of the sections of your review, for example: introduction, methods, results, etc.

Useful PRISMA links: 

• PRISMA Checklist  (checklist of sections to include in your systematic review, eg: methods, results, etc.) 
• PRISMA flow chart   (charts the number of records identified, included and excluded, and the reasons for exclusions.)
• Citing PRISMA

Cochrane Handbook 

Cochrane Handbook for Systematic Reviews of Interventions  

Choosing a systematic review standard/guideline

The School of Psychology recommends its students follow the PRISMA reporting guidance when conducting a systematic review, but it is also helpful to read through the Cochrane Handbook of Systematic Review, particularly if your research topic spans both medical and human sciences.
