Annotated Bibliographies

What this handout is about.

This handout will explain why annotated bibliographies are useful for researchers, provide an explanation of what constitutes an annotation, describe various types of annotations and styles for writing them, and offer multiple examples of annotated bibliographies in the MLA, APA, and CBE/CSE styles of citation.

Introduction

Welcome to the wonderful world of annotated bibliographies! You’re probably already familiar with the need to provide bibliographies, reference pages, and works cited lists to credit your sources when you do a research paper. An annotated bibliography includes descriptions and explanations of your listed sources beyond the basic citation information you usually provide.

Why do an annotated bibliography?

One of the reasons behind citing sources and compiling a general bibliography is so that you can prove you have done some valid research to back up your argument and claims. Readers can refer to a citation in your bibliography and then go look up the material themselves. When inspired by your text or your argument, interested researchers can access your resources. They may wish to double check a claim or interpretation you’ve made, or they may simply wish to continue researching according to their interests. But think about it: even though a bibliography provides a list of research sources of all types that includes publishing information, how much does that really tell a researcher or reader about the sources themselves?

An annotated bibliography provides specific information about each source you have used. As a researcher, you have become an expert on your topic: you have the ability to explain the content of your sources, assess their usefulness, and share this information with others who may be less familiar with them. Think of your paper as part of a conversation with people interested in the same things you are; the annotated bibliography allows you to tell readers what to check out, what might be worth checking out in some situations, and what might not be worth spending the time on. It’s kind of like providing a list of good movies for your classmates to watch and then going over the list with them, telling them why this movie is better than that one or why one student in your class might like a particular movie better than another student would. You want to give your audience enough information to understand basically what the movies are about and to make an informed decision about where to spend their money based on their interests.

What does an annotated bibliography do?

A good annotated bibliography:

• encourages you to think critically about the content of the works you are using, their place within a field of study, and their relation to your own research and ideas.
• proves you have read and understand your sources.
• establishes your work as a valid source and you as a competent researcher.
• situates your study and topic in a continuing professional conversation.
• provides a way for others to decide whether a source will be helpful to their research if they read it.
• could help interested researchers determine whether they are interested in a topic by providing background information and an idea of the kind of work going on in a field.

What elements might an annotation include?

• Bibliography according to the appropriate citation style (MLA, APA, CBE/CSE, etc.).
• Explanation of main points and/or purpose of the work—basically, its thesis—which shows among other things that you have read and thoroughly understand the source.
• Verification or critique of the authority or qualifications of the author.
• Comments on the worth, effectiveness, and usefulness of the work in terms of both the topic being researched and/or your own research project.
• The point of view or perspective from which the work was written. For instance, you may note whether the author seemed to have particular biases or was trying to reach a particular audience.
• Relevant links to other work done in the area, like related sources, possibly including a comparison with some of those already on your list. You may want to establish connections to other aspects of the same argument or opposing views.

The first four elements above are usually a necessary part of the annotated bibliography. Points 5 and 6 may involve a little more analysis of the source, but you may include them in other kinds of annotations besides evaluative ones. Depending on the type of annotation you use, which this handout will address in the next section, there may be additional kinds of information that you will need to include.

For more extensive research papers (probably ten pages or more), you often see resource materials grouped into sub-headed sections based on content, but this probably will not be necessary for the kinds of assignments you’ll be working on. For longer papers, ask your instructor about their preferences concerning annotated bibliographies.

Did you know that annotations have categories and styles?

Decisions, decisions.

As you go through this handout, you’ll see that, before you start, you’ll need to make several decisions about your annotations: citation format, type of annotation, and writing style for the annotation.

First of all, you’ll need to decide which kind of citation format is appropriate to the paper and its sources, for instance, MLA or APA. This may influence the format of the annotations and bibliography. Typically, bibliographies should be double-spaced and use normal margins (you may want to check with your instructor, since they may have a different style they want you to follow).

MLA (Modern Language Association)

See the UNC Libraries citation tutorial for basic MLA bibliography formatting and rules.

• MLA documentation is generally used for disciplines in the humanities, such as English, languages, film, and cultural studies or other theoretical studies. These annotations are often summary or analytical annotations.
• Title your annotated bibliography “Annotated Bibliography” or “Annotated List of Works Cited.”
• Following MLA format, use a hanging indent for your bibliographic information. This means the first line is not indented and all the other lines are indented four spaces (you may ask your instructor if it’s okay to tab over instead of using four spaces).
• Begin your annotation immediately after the bibliographic information of the source ends; don’t skip a line down unless you have been told to do so by your instructor.

APA (American Psychological Association)

See the UNC Libraries citation tutorial for basic APA bibliography formatting and rules.

• Natural and social sciences, such as psychology, nursing, sociology, and social work, use APA documentation. It is also used in economics, business, and criminology. These annotations are often succinct summaries.
• Annotated bibliographies for APA format do not require a special title. Use the usual “References” designation.
• Like MLA, APA uses a hanging indent: the first line is set flush with the left margin, and all other lines are indented four spaces (you may ask your instructor if it’s okay to tab over instead of using four spaces).
• After the bibliographic citation, drop down to the next line to begin the annotation, but don’t skip an extra line.
• The entire annotation is indented an additional two spaces, so that means each of its lines will be six spaces from the margin (if your instructor has said that it’s okay to tab over instead of using the four spaces rule, indent the annotation two more spaces in from that point).

CBE (Council of Biology Editors)/CSE (Council of Science Editors)

See the UNC Libraries citation tutorial for basic CBE/CSE bibliography formatting and rules.

• CBE/CSE documentation is used by the plant sciences, zoology, microbiology, and many of the medical sciences.
• Annotated bibliographies for CBE/CSE format do not require a special title. Use the usual “References,” “Cited References,” or “Literature Cited,” and set it flush with the left margin.
• Bibliographies for CSE in general are in a slightly smaller font than the rest of the paper.
• When using the name-year system, as in MLA and APA, the first line of each entry is set flush with the left margin, and all subsequent lines, including the annotation, are indented three or four spaces.
• When using the citation-sequence method, each entry begins two spaces after the number, and every line, including the annotation, will be indented to match the beginning of the entry, or may be slightly further indented, as in the case of journals.
• After the bibliographic citation, drop down to the next line to begin the annotation, but don’t skip an extra line. The entire annotation follows the indentation of the bibliographic entry, whether it’s N-Y or C-S format.
• Annotations in CBE/CSE are generally a smaller font size than the rest of the bibliographic information.

After choosing a documentation format, you’ll choose from a variety of annotation categories presented in the following section. Each type of annotation highlights a particular approach to presenting a source to a reader. For instance, an annotation could provide a summary of the source only, or it could also provide some additional evaluation of that material.

In addition to making choices related to the content of the annotation, you’ll also need to choose a style of writing—for instance, telescopic versus paragraph form. Your writing style isn’t dictated by the content of your annotation. Writing style simply refers to the way you’ve chosen to convey written information. A discussion of writing style follows the section on annotation types.

Types of annotations

As you now know, one annotation does not fit all purposes! There are different kinds of annotations, depending on what might be most important for your reader to learn about a source. Your assignments will usually make it clear which citation format you need to use, but they may not always specify which type of annotation to employ. In that case, you’ll either need to pick your instructor’s brain a little to see what they want or use clue words from the assignment itself to make a decision. For instance, the assignment may tell you that your annotative bibliography should give evidence proving an analytical understanding of the sources you’ve used. The word analytical clues you in to the idea that you must evaluate the sources you’re working with and provide some kind of critique.

Summary annotations

There are two kinds of summarizing annotations, informative and indicative.

Summarizing annotations in general have a couple of defining features:

• They sum up the content of the source, as a book report might.
• They give an overview of the arguments and proofs/evidence addressed in the work and note the resulting conclusion.
• They do not judge the work they are discussing. Leave that to the critical/evaluative annotations.
• When appropriate, they describe the author’s methodology or approach to material. For instance, you might mention if the source is an ethnography or if the author employs a particular kind of theory.

Informative annotation

Informative annotations sometimes read like straight summaries of the source material, but they often spend a little more time summarizing relevant information about the author or the work itself.

Indicative annotation

Indicative annotation is the second type of summary annotation, but it does not attempt to include actual information from the argument itself. Instead, it gives general information about what kinds of questions or issues are addressed by the work. This sometimes includes the use of chapter titles.

Critical/evaluative

Evaluative annotations don’t just summarize. In addition to tackling the points addressed in summary annotations, evaluative annotations:

• evaluate the source or author critically (biases, lack of evidence, objective, etc.).
• show how the work may or may not be useful for a particular field of study or audience.
• explain how researching this material assisted your own project.

Combination

An annotated bibliography may combine elements of all the types. In fact, most of them fall into this category: a little summarizing and describing, a little evaluation.

Writing style

Ok, next! So what does it mean to use different writing styles as opposed to different kinds of content? Content is what belongs in the annotation, and style is the way you write it up. First, choose which content type you need to compose, and then choose the style you’re going to use to write it

This kind of annotated bibliography is a study in succinctness. It uses a minimalist treatment of both information and sentence structure, without sacrificing clarity. Warning: this kind of writing can be harder than you might think.

Don’t skimp on this kind of annotated bibliography. If your instructor has asked for paragraph form, it likely means that you’ll need to include several elements in the annotation, or that they expect a more in-depth description or evaluation, for instance. Make sure to provide a full paragraph of discussion for each work.

As you can see now, bibliographies and annotations are really a series of organized steps. They require meticulous attention, but in the end, you’ve got an entire testimony to all the research and work you’ve done. At the end of this handout you’ll find examples of informative, indicative, evaluative, combination, telescopic, and paragraph annotated bibliography entries in MLA, APA, and CBE formats. Use these examples as your guide to creating an annotated bibliography that makes you look like the expert you are!

Explanation, Process, Directions, and Examples

What is an annotated bibliography.

An annotated bibliography is a list of citations to books, articles, and documents. Each citation is followed by a brief (usually about 150 words) descriptive and evaluative paragraph, the annotation. The purpose of the annotation is to inform the reader of the relevance, accuracy, and quality of the sources cited.

Annotations vs. Abstracts

Abstracts are the purely descriptive summaries often found at the beginning of scholarly journal articles or in periodical indexes. Annotations are descriptive and critical; they may describe the author's point of view, authority, or clarity and appropriateness of expression.

The Process

Creating an annotated bibliography calls for the application of a variety of intellectual skills: concise exposition, succinct analysis, and informed library research.

First, locate and record citations to books, periodicals, and documents that may contain useful information and ideas on your topic. Briefly examine and review the actual items. Then choose those works that provide a variety of perspectives on your topic.

Cite the book, article, or document using the appropriate style.

Write a concise annotation that summarizes the central theme and scope of the book or article. Include one or more sentences that (a) evaluate the authority or background of the author, (b) comment on the intended audience, (c) compare or contrast this work with another you have cited, or (d) explain how this work illuminates your bibliography topic.

Critically Appraising the Book, Article, or Document

For guidance in critically appraising and analyzing the sources for your bibliography, see How to Critically Analyze Information Sources . For information on the author's background and views, ask at the reference desk for help finding appropriate biographical reference materials and book review sources.

Choosing the Correct Citation Style

Check with your instructor to find out which style is preferred for your class. Online citation guides for both the Modern Language Association (MLA) and the American Psychological Association (APA) styles are linked from the Library's Citation Management page .

Sample Annotated Bibliography Entries

The following example uses APA style ( Publication Manual of the American Psychological Association , 7th edition, 2019) for the journal citation:

Waite, L., Goldschneider, F., & Witsberger, C. (1986). Nonfamily living and the erosion of traditional family orientations among young adults. American Sociological Review, 51 (4), 541-554. The authors, researchers at the Rand Corporation and Brown University, use data from the National Longitudinal Surveys of Young Women and Young Men to test their hypothesis that nonfamily living by young adults alters their attitudes, values, plans, and expectations, moving them away from their belief in traditional sex roles. They find their hypothesis strongly supported in young females, while the effects were fewer in studies of young males. Increasing the time away from parents before marrying increased individualism, self-sufficiency, and changes in attitudes about families. In contrast, an earlier study by Williams cited below shows no significant gender differences in sex role attitudes as a result of nonfamily living.

This example uses MLA style ( MLA Handbook , 9th edition, 2021) for the journal citation. For additional annotation guidance from MLA, see 5.132: Annotated Bibliographies .

Waite, Linda J., et al. "Nonfamily Living and the Erosion of Traditional Family Orientations Among Young Adults." American Sociological Review, vol. 51, no. 4, 1986, pp. 541-554. The authors, researchers at the Rand Corporation and Brown University, use data from the National Longitudinal Surveys of Young Women and Young Men to test their hypothesis that nonfamily living by young adults alters their attitudes, values, plans, and expectations, moving them away from their belief in traditional sex roles. They find their hypothesis strongly supported in young females, while the effects were fewer in studies of young males.

Components of an Annotated Bibliography

An annotated bibliography is an APA reference list that includes a brief summary and analysis -- the annotation --  under the reference entry.  

An annotated bibliography includes:

• APA Title page
• Pages are numbered beginning with title page
• References centered and bolded at top of page
• Entries listed in alphabetical order
• Annotations begin under its associated reference
• Annotations are indented 0.5 inches from the left margin
• The entire document is double spaced; no extra space between entries

Example of an annotated bibliography entry:

An  an n otated bibliography is composed of the full APA reference for a source followed by notes and commentary about that so urce. T he word  “annotate” means “critical or explanatory notes” and the word “bibliography” means “a list of sources”.  Annotation s are meant to be critical in addition to being descriptive.

Annotations are generally between five to seven sentences in length and appear directly under the APA reference.  The entire annotation is indented 0.5 inch from the left margin and lines up with the hanging indent of the APA reference.

Use the question prompts below as a guide when writing annotations:

• 2 to 4 sentences to  summarize   the main idea(s) of the source.

     - What are the main arguments?

     - What is the point of this book/article?

     - What topics are covered?

• 1 or 2 sentences to  assess   and  evaluate   the source.

     - How does it compare with other sources in your bibliography?

     - Is this information reliable? current?

     - Is the author credible? have the background to write on this topic?

     - Is the source objective or biased?

• 1 or 2 sentences to  reflect   on the source.

     - Was this source helpful to you?

     - How can you use this source for your research project?

     - Has it changed how you think about your topic?

• a title page, and
• the annotated bibliography which begins on its own page with the word References bolded and centered at the top of the page.

Each entry begins with an APA reference for the resource with the annotation appearing directly beneath. The entire annotation is indented 0.5 inches from the left margin.

Entries are listed in alphabetical order. The entire document is typed on one of the six approved font styles and sizes and is double spaced.  There is no additional space between entires.

Consider using Academic Writer or NoodleTools to create and format your annotated bibliography.

How to Write an Annotated Bibliography - MLA Style

What is an annotation, how is an annotation different from an abstract, what is an annotated bibliography, types of annotated bibliographies, descriptive or informative, analytical or critical, to get started.

An annotation is more than just a brief summary of an article, book, website, or other type of publication. An annotation should give enough information to make a reader decide whether to read the complete work. In other words, if the reader were exploring the same topic as you, is this material useful and if so, why?

While an abstract also summarizes an article, book, website, or other type of publication, it is purely descriptive. Although annotations can be descriptive, they also include distinctive features about an item. Annotations can be evaluative and critical and the two major types of annotations included here demonstrate the difference.

An annotated bibliography is an organized list of sources (like a reference list). It differs from a straightforward bibliography in that each reference is followed by a paragraph length annotation, usually 100–200 words in length.

Depending on the assignment, an annotated bibliography might have different purposes:

• Provide a literature review on a particular subject
• Help to formulate a thesis on a subject
• Demonstrate the research you have performed on a particular subject
• Provide examples of major sources of information available on a topic
• Describe items that other researchers may find of interest on a topic

There are two major types of annotated bibliographies:

A descriptive or informative annotated bibliography describes or summarizes a source as does an abstract; it describes why the source is useful for researching a particular topic or question and its distinctive features. In addition, it describes the author's main arguments and conclusions without evaluating what the author says or concludes.

For example:

Gabbin, Joanne V. "Maya Angelou--The Peoples' Poet Laureate: An Introduction."  Langston Hughes Review , vol. 19, Spring 2005, pp. 3-6.  LION: Literature Online , gateway.proquest.com/openurl?ctx_ver=Z39.88-2003&xri:pqil:res_ver=0.2&res_id=xri:lion&rft_id=xri:lion:ft:criticism:R04012678:0&rft.accountid=14580. This scholarly article is a critical introduction to the works of Maya Angelou, and the criteria surrounding her success as a poet laureate. The author points out Angelou's literary influences, which include William Shakespeare, Edgar Allan Poe, Douglas Johnson, Langston Hughes, among others. This article also points out that her poetry lacks cultural boundaries, yet her trademark lies in the secular chants, songs, and games of the black vernacular tradition. The author discusses dialect and vernacular rhythms in several of Angelou's poems, and compares several of her works to the racy dialect of Sterling Brown and Langston Hughes. Also discussed is her political cultural voice and her deep understanding of emotion. This article is distinctive in its discussion of the need for a poet laureate to add to an audience's collective memory.

Please pay attention to the last sentence. While it points out distinctive features about the item it does not analyze the author's conclusions.

An analytical or critical annotation not only summarizes the material, it analyzes what is being said. It examines the strengths and weaknesses of what is presented as well as describing the applicability of the author's conclusions to the research being conducted.

Analytical or critical annotations will most likely be required when writing for a college-level course.

Gabbin, Joanne V. "Maya Angelou--The Peoples' Poet Laureate: An Introduction."  Langston Hughes Review , vol. 19, Spring 2005, pp. 3-6.  LION: Literature Online , gateway.proquest.com/openurl?ctx_ver=Z39.88-2003&xri:pqil:res_ver=0.2&res_id=xri:lion&rft_id=xri:lion:ft:criticism:R04012678:0&rft.accountid=14580. This scholarly article is a critical introduction to the works of Maya Angelou, and the criteria surrounding her success as a poet laureate. The author points out Angelou's literary influences, that include William Shakespeare, Edgar Allan Poe, Douglas Johnson, Langston Hughes, among others. This article also points out that her poetry lacks cultural boundaries, yet her trademark lies in the secular chants, songs, and games of the black vernacular tradition. The author discusses dialect and vernacular rhythms in several of Angelou's poems, and compares several of her works to the racy dialect of Sterling Brown and Langston Hughes. Also discussed is her political cultural voice and her deep understanding of emotion. This article is a good resource for those wanting to explore criteria related to the achievement of the award of poet laureate and how Angelou meets the criteria. This article begins to explore the poet's works and suggests her ability to add to an audience's collective memory. The author is a professor of English at James Madison University and has authored a book on Sterling Brown and numerous critical essays.

Please pay attention to the last three sentences. They give information about the author and critique the author's research.

To write an annotated bibliography here are the steps:

• Choose your sources -  Before writing your annotated bibliography, you must choose your sources. This involves doing research much like for any other project. Locate records to materials that may apply to your topic.
• Review the items -  Then review the actual items and choose those that provide a wide variety of perspectives on your topic. Article abstracts are helpful in this process.
• The purpose of the work
• A summary of its content
• Information about the author(s)
• For what type of audience the work is written
• Its relevance to the topic
• Any special or unique features about the material
• Research methodology
• The strengths, weaknesses or biases in the material

Annotated bibliographies are arranged alphabetically by the first author's last name.

Please see the  MLA Examples Page  for more information on citing in MLA style.

Annotated Bibliographies

What Is An Annotated Bibliography?

What is an annotated bibliography.

An annotated bibliography is a list of citations (references) to books, articles, and documents followed by a brief summary, analysis or evaluation, usually between 100-300 words, of the sources that are cited in the paper.  This summary provides a description of the contents of the source and may also include evaluative comments, such as the relevance, accuracy and quality of the source.  These summaries are known as annotations. 

• Annotated bibliographies are completed before a paper is written
• They can be stand-along assignments
• They can be used as a reference tool as a person works on their paper

Annotations vs. Abstracts

Abstracts are the descriptive summaries of article contents found at the beginning of scholarly journal articles that are written by the article author(s) or editor. Their purpose is to inform a reader about the topic, methodology, results and conclusion of the research of the article's author(s).  The summaries are provided so that a researcher can determine whether or not the article may have information of interest to them.  Abstracts do not serve an evaluative purpose.

Annotations found in bibliographies are evaluations of sources cited in a paper.  They describe a work, but also critique the source by examining the author’s point of view, the strengths and weakness of the research or article hypothesis or how well the author presented their research or findings.

How to write an annotated bibliography

The creation of an annotated bibliography is a three-step process. It starts with finding and evaluating sources for your paper. Next is choosing the type or category of annotation, then writing the annotation for each different source. The final step is to choose a citation style for the bibliography.

Types of Annotated Bibliographies

Types of Annotations

Annotations come in different types, the one to use depends on the instructor’s assignment.  Annotations can be descriptive, a summary, or an  evaluation or a combination of descriptive and evaluation.

Descriptive/Summarizing Annotations

There are two kinds of descriptive or summarizing annotations, informative or indicative, depending on what is most important for a reader to learn about a source.  Descriptive/summarizing annotations provide a brief overview or summary of the source. This can include a description of the contents and a statement of the main argument or position of the article as well as a summary of the main points.  It may also describe why the source would be useful for the paper’s topic or question. 

Indicative annotations provide a quick overview of the source, the kinds of questions/topics/issues or main points that are addressed by the source, but do not include information from the argument or position itself.

Informative annotations, like indicative annotations, provide a brief summary of the source.   In addition, an informative annotation identifies the hypothesis, results, and conclusions presented by the source.  When appropriate, they describe the author’s methodology or approach to the topic under discussion.  However, they do not provide information about the sources usefulness to the paper or contains analytical or critical information about the source’s quality. 

Evaluative Annotations (also known as critical or analytical)

Evaluative annotations go beyond just summarizing the source and listing out it’s key points, but also analyzes the content. It looks at the strengths and weaknesses of the article’s argument, the reliability of the presented information as well as any biases of the author. It talks about how the source may be useful to a particular field of study or the person’s research project.

Combination Annotations

Combination annotations “combine” aspects from indicative/informative and evaluative annotations and are the most common category of annotated bibliography.  Combination annotations include one to two sentences summarizing or describing content, in addition to one or more sentences providing an critical evaluation.

Writing Style for Annotations

Annotations typically follow three specific formats depending on how long they are.

• Phrases – Short phrases providing the information in a quick, concise manner.
• Sentences – Complete sentences with proper punctuation and grammar, but are short and concise.
• Paragraphs – Longer annotations break the information out into different paragraphs. This format is very effective for combination annotations.

To sum it up:

An annotation may include the following information:

• A brief summary or overview of the source content
• The source’s strengths and weaknesses in presenting the argument or position
• Its conclusions
• Why the source is relevant in to field of study of the paper
• Its relationships to other studies in the field
• An evaluation of the research methodology (if applicable)
• Information about the author’s background and potential biases
• Conclusions about the usefulness of the source for the paper

Critically Analyzing Articles

In order to write an annotation for a paper source, you need to first read and then critically analyze it:

• Try to identify the topic of the source -- what is it about and is it clearly stated.
• See if you can identify the purpose of the author(s) in doing the research or writing about the topic. Is it to survey and summarize research on a topic?  Is the author(s) presenting an argument based on previous research, or refuting previously published research?
• Identify the research methods used and try to identify whether they appear to be suitable or not for the stated purpose of the research.  
• Was the research reported in a consistent or clear manner?  Or, was the author's argument/position presented in a consistent or convincing manner? Did the author(s) fail to acknowledge and explain any limitations?
• Was the logic of the research/argument claims properly supported with convincing evidence/analysis/data? Did you spot any fallacies?
• Check whether the author(s) refers to other research and if similar studies have been done. 
• If illustrations or charts are used, are they effective in presenting information?
• Analyze the sources that were used by the author(s). Did the author(s) miss any important studies they should have considered?
• Your opinion of the source -- do you agree with or are convinced of the findings?  
• Your estimation of the source’s contribution to knowledge and its implications or applications to the field of study.

Formatting An Annotated Bibliography

How do I format my annotated bibliography?

An annotated bibliography entry consists of two components: the Citation and the Annotation.

The citation should be formatted in the bibliographic style that your instructor has requested for the paper. Some common citation styles include APA, MLA, and Chicago. For more information on citation styles, see Writing Guides, Style Manuals and the Publication Process in the Biological & Health Sciences .

Many databases (e.g., PubMed, Academic Search Premier, Library Search on library homepage, and Google Scholar) offer the option of creating your references in various citation styles. 

Look for the "cite" link -- see examples for the following resources:

This article focuses on the role of social capital in responsible leadership. It looks at both the social networks that a leader builds within an organization, and the links that a leader creates with external stakeholders. Maak’s main aim with this article seems to be to persuade people of the importance of continued research into the abilities that a leader requires and how they can be acquired. The focus on the world of multinational business means that for readers outside this world many of the conclusions seem rather obvious (be part of the solution not part of the problem). In spite of this, the article provides useful background information on the topic of responsible leadership and definitions of social capital which are relevant to an analysis of a public servant.

     Herbert London, the Dean of Journalism at New York University and author of several books and articles, explains how television contradicts five commonly believed ideas. He uses specific examples of events seen on television, such as the assassination of John Kennedy, to illustrate his points. His examples have been selected to contradict such truisms as: “seeing is believing”; “a picture is worth a thousand words”; and “satisfaction is its own reward.” London uses logical arguments to support his ideas which are his personal opinion. He does not refer to any previous works on the topic. London’s style and vocabulary would make the article of interest to any reader. The article clearly illustrates London’s points, but does not explore their implications leaving the reader with many unanswered questions.

Annotated Bibliographies

What is an annotated bibliography, creating an annotated bibliography, what about formatting, sample papers.

An annotated bibliography is a list of citations to sources, such as books and articles. Each citation is followed by an annotation, a brief descriptive and evaluative paragraph about 150 words long, that analyzes the source. An annotated bibliography usually looks like any other bibliography with alphabetized citations of sources, except that here each source is followed by an explanatory paragraph. The purpose of the annotation is to inform on the relevance, accuracy, and quality of the sources cited, and this work can form the basis of a literature review later in the writing process.

Types of annotations 

• Descriptive: states the topic of the source only
• Evaluative: evaluates the source, which may include placing the work in context of other research or evaluating its usefulness. This is the type expected for most research assignments. 
• Summary: summarizes the source but does not take a stance or make an argument about the source.

Select Topic

Your topic should be neither too broad nor too narrow, but engage with a specific research question. You may not have a thesis but will form one in the course of reading sources. Consider some strategies for selecting and refining a topic.

Locate Sources 

This is a time-consuming process when writing an annotated bibliography. You are looking for sources that work together to support or refute your research question, not just the first few sources available. You should also consider a variety of sources, including books, articles, primary sources, and reference materials. Check the Research Guide in your discipline for suggestions. 

Read and Evaluate Sources

Evaluating a source is about more than reading the abstract. As part of the annotation, you should provide the following information: a summary of the source, the intended audience, a critical evaluation of the argument, and a contextual analysis of how it fits in your own research. 

Create Citations 

The citation is the first piece of information a reader will see, and should conform to one of the major citation style guides . Most guides require a "hanging first line," whereby the first line of the citation sits further to the right on the page with subsequent lines indented. This is a special indentation feature offered in the paragraph formatting section of Word (or other word-processing software). Don't try to indent by just adding spaces.

Write Annotations

Each annotation immediately follows the citation, and consists of a short, evaluative paragraph. It can include a very brief summary of the source, along with information about the author(s) and intended audience, followed by a critical analysis of the source in relation to your topic and research question. 

Ask yourself: Does it cover my topic? Is it a good representation of the sources available on the topic?  An annotated bibliography isn't only a list of sources; the annotations should indicate some relationship between the sources and how they work together in the context of your research. 

Style and Format 

As a final check, be sure all the citations are formatted in accordance with your chosen style guide. Also make sure the overall organization of the bibliography makes sense in the context of the research question. 

Most of the major citation styles call for a hanging first line on annotated bibliographies. This means the first line of the citation will align with the left margin of the page, and all subsequent lines of the citation and annotation will indent to the right.

This article discusses the growth of the aquaculture sector in Maine and analyzes the overlap between commercial fishing licenses and aquaculture leases and licenses to determine the extent to which commercial fishers are diversifying into aquaculture. A small percentage of commercial fishers are licensed to do aquaculture and instead, those getting into aquaculture appear to be a new group of ocean users. This has implications for efforts to diversify commercial fishing-dependent livelihoods as a response to climate change impacts. This is relevant to my research in which I am exploring the potential for aquaculture to be a diversification strategy for commercial fishermen. I will likely use this source as supporting evidence that such a transition does not currently appear to be taking place other than for a minority of commercial fishermen.

Introduction

1. Definition

A bibliography is usually thought of as an alphabetical listing of books at the end of a written work (book, book chapter, or article), to which the author referred during the research and writing process. In addition to books, bibliographies can include sources such as articles, reports, interviews, or even non-print resources like Web sites, video or audio recordings. Because they may include such varied resources, bibliographies are also referred to as 'references', 'works cited' or 'works consulted' (the latter can include those titles that merely contributed to research, but were not specifically cited in text). The standard bibliography details the citation information of the consulted sources: author(s), date of publication, title, and publisher's name and location (and for articles: journal title, volume, issue and page numbers). The primary function of bibliographic citations is to assist the reader in finding the sources used in the writing of a work.

To these basic citations, the annotated bibliography adds descriptive and evaluative comments (i.e., an annotation ), assessing the nature and value of the cited works. The addition of commentary provides the future reader or researcher essential critical information and a foundation for further research.

2. Composition

While an annotation can be as short as one sentence, the average entry in an annotated bibliography consists of a work's citation information followed by a short paragraph of three to six sentences, roughly 150 words in length. Similar to the literature review except for the shorter length of its entries, the annotated bibliography is compiled by:

• Considering scope: what types of sources (books, articles, primary documents, Web sites, non-print materials) will be included? how many (a sampling or a comprehensive list)? (Your instructor may set these guidelines)
• Conducting a search for the sources and retrieving them
• Evaluating retrieved sources by reading them and noting your findings and impressions
• Once a final group of sources has been selected, giving full citation data (according to the bibliographic style [e.g., APA, Chicago, MLA] prescribed by your instructor) and writing an annotation for each source; do not list a source more than once

Annotations begin on the line following the citation data and may be composed with complete sentences or as verb phrases (the cited work being understood as the subject)—again at the discretion of the instructor. The annotation should include most, if not all, of the following:

• Explanation of the main purpose and scope of the cited work
• Brief description of the work's format and content
• Theoretical basis and currency of the author's argument
• Author's intellectual/academic credentials
• Work's intended audience
• Value and significance of the work as a contribution to the subject under consideration
• Possible shortcomings or bias in the work
• Any significant special features of the work (e.g., glossary, appendices, particularly good index)
• Your own brief impression of the work

Although these are many of the same features included in a literature review, the emphasis of bibliographic annotation should be on brevity.

Not to be confused with the abstract —which merely gives a summary of the main points of a work—the annotated bibliography always describes and often evaluates those points. Whether an annotated bibliography concludes an article or book—or is even itself a comprehensive, book-length listing of sources—its purposes are the same:

• To illustrate the scope and quality of one's own research
• To review the literature published on a particular topic
• To provide the reader/researcher with supplementary, illustrative or alternative sources
• To allow the reader to see if a particular source was consulted
• To provide examples of the type of resources available on a given topic
• To place original research in a historical context

Annotated Bibliography: How to Write...: Home

Phase 1: Understanding Your Needs

  so, what is an annotation.

An annotation is more than just a brief summary of an article, book, Web site or other type of publication. An annotation should give enough information to make a reader decide whether to read the complete work. In other words, if the reader were exploring the same topic as you, is this material useful and if so, why?

  How is an annotation different from an abstract?

While an abstract also summarizes an article, book, Web site or other type of publication, it is purely descriptive. Although annotations can be descriptive, they also include distinctive features about an item. Annotations can be evaluative and critical as we will see when we look at the two major types of annotations.

  What is an annotated bibliography?

An annotated bibliography is an organized list of sources (like a reference list). It differs from a straightforward bibliography in that each reference is followed by a paragraph length annotation, usually 100–200 words in length.

  Depending on the assignment, an annotated bibliography might have different purposes:

• Provide a literature review on a particular subject
• Help to formulate a thesis on a subject
• Demonstrate the research you have performed on a particular subject
• Provide examples of major sources of information available on a topic
• Describe items that other researchers may find of interest on a topic

  Types of annotated bibliographies

There are two major types of annotated bibliographies:

• Descriptive or informative (see below)
• Analytical or critical  (see  below)

Phase 2: Getting Started

  what's next.

Now that you have reviewed the information for Phase 1, you are ready to begin writing your own annotated bibliography.

• Choose your sources.  Before writing your annotated bibliography, you must choose your sources. This involves doing research much like for any other project. Locate records to materials that may apply to your topic.
• Review the items.  Then review the actual items and choose those that provide a wide variety of perspectives on your topic. Article abstracts are helpful in this process.
• Write the citation and annotation. When writing your annotation, the complete citation should always come first and the annotation follows. Depending on the type of annotated bibliography you are writing, you will want to include:
• The purpose of the work
• A summary of its content
• For what type of audience the work is written
• Its relevance to the topic
• Any special or unique features about the material
• The strengths, weaknesses or biases in the material

Annotated bibliographies may be arranged alphabetically or chronologically, check with your instructor to see what he or she prefers.

  Guidelines for formatting the citations

Remember, the citations themselves must be formatted properly. Visit the Help Guides that Marshall University have prepared for you to help with your citation formatting:

• APA 7 Quick Guide (PDF)
• MLA 8 Quick Guide (PDF)
• Turabian Quick Guide (PDF)
• MU Libraries Citation Help (web)

Remember to check with your instructor if you are unsure which style to use.

The Two Types of Annotated Bibliographies

A descriptive or informative annotated bibliography describes or summarizes a source, similar to an abstract; it describes why the source is useful for researching a particular topic or question; and, it lists the article's distinctive features. In addition, it describes the author's main arguments and conclusions without evaluating what the author says or concludes.

For example:

Breeding evil. (2005, August 6).  Economist , 376(8438), 9. Retrieved from http://www.economist.com

This editorial from the Economist describes the controversy surrounding video games and the effect they have on people who use them. The author points out that skepticism of new media have gone back to the time of the ancient Greeks, so this controversy surrounding video games is nothing new. The article also points out that most critics of gaming are people over 40 and it is an issue of generations not understanding one another, rather than of the games themselves. As the youth of today grow older, the controversy will die out, according to the author. The author of this article stresses the age factor over violence as the real reason for opposition to video games and stresses the good that gaming has done in most areas of human life. This article is distinctive in exploring the controversy surrounding video games from a generational standpoint and is written for a general audience.

Please pay attention to the last sentence . While it points out distinctive features about the item, it does not analyze the author's conclusions.

An analytical or critical annotation not only summarizes the material, it also analyzes what is being said. It examines the strengths and weaknesses of what is presented as well as describing the applicability of the author's conclusions to the research being conducted.

It is likely that, for most of your annotated bibliographies, you will be writing analytical or critical annotations.

This editorial from the Economist describes the controversy surrounding video games and the effect they have on people who use them. The article points out that most critics of gaming are people over 40 and it is an issue of age not of the games themselves. While the author briefly mentions studies done around the issue of violence and gaming, he does not go into enough depth for the reader to truly know the range of studies that have actually been done in this area, other than to take his word that the research is unsatisfactory. The author of this article stresses the age factor over violence as the real reason for opposition to video games and stresses the good gaming has done in most areas of human life. This article is a good resource for those wanting to begin to explore the controversy surrounding video games, however for anyone doing serious research, one should actually examine some of the research studies that have been done in this area rather than simply take the author's word that opposition to video games is simply due to an issue of generational divide.

Please pay attention to the last sentence . It criticizes the author's research.

Please note that in these samples, the citations follow the APA format. Your instructor may require you to use another citation format, such as MLA, so always check the assignment requirements first.

An  annotated bibliography  is a  bibliography  that also include a paragraph following each citation that summarizes or evaluates the source being cited. " Each annotation is generally three to seven sentences long. In some bibliographies, the annotation merely describes the content and scope of the source; in others, the annotation also evaluates the source’s reliability, currency, and relevance to a researcher’s purpose" ( Glossary of Research Terms , n.d.). 

The primary purpose of bibliographic citations is to assist the reader in finding the sources used in the writing of a work . Depending on the assignment, an annotated bibligraphy might have different purposes:

• provide a literature review on a particular subject
• help formulate a thesis on a subject
• demonstrate the quality of research that you have done
• show that you understand each source cited
• provide examples of the types of sources available
• describe other items on a topic that may be of interest to the reader
• explore the subject for further research

Video was created by Carleton University Library

There are 2 common types of annotations -  descriptive  and  critical .

"Descriptive  annotation may summarize:

• The main purpose or idea of the work
• The contents of the work
• The author’s conclusions
• The intended audience
• The author’s research methods
• Special features of the work such as illustrations, maps, tables, etc." ( University of Wisconsin , 2010)

"Critical  annotation includes the same information as a descriptive annotation, but will also include value judgments or comments on the effectiveness of the work. [In this context, critical means evaluative and may include both positive and negative comments.] When writing a critical annotation, include some of the these features:

• The importance of the work’s contribution to the literature of the subject
• The author’s bias or tone
• The author’s qualifications for writing the work
• The accuracy of the information in the source
• Limitations or significant omissions
• The work’s contribution to the literature of the subject
• Comparison with other works on the topic" ( University of Wisconsin , 2010)

The citations (bibliographic information - title, date, author, publisher, etc.) in the annotated bibliography are formatted using the particular style manual (APA, MLA, Chicago, etc.) that your discipline requires.

Annotations are written in paragraph form, usually 3-7 sentences (or 80-200 words). Depending on your assignment your annotations will generally include the following:

• Summary: Summarize the information given in the source. Note the intended audience. What are the main arguments? What is the point of this book or article? What topics are covered? If someone asked what this article/book is about, what would you say?
• Evaluate/Assess: Is this source credible? Who wrote it? What are their credentials? Who is the publisher? Is it a useful source? How does it compare with other sources in your bibliography? Is the information reliable? Is this source biased or objective? What is the goal of this source?
• Reflect/React:  Once you've summarized and assessed a source, you need to ask how it fits into your research. State your reaction and any additional questions you have about the information in your source.  Was this source helpful to you? How does it help you shape your argument? How can you use this source in your research project? Has it changed how you think about your topic. Compare each source to other sources in your AB in terms of its usefulness and thoroughness in helping answer your research question.

When creating an annotated bibliography you will need to know how to summarize and analyze, and know how to do library research.

• Develop a research question and thesis, and come up with search terms (keywords).
• Locate citations to books, periodicals, and documents that may contain useful information and ideas on your topic.
• Briefly examine and review the actual items (learn about how to critically analyze information ). Then choose those works that provide a variety of perspectives on your topic.
• Read  the items that are most appropriate.
• Cite the book, article, or document using the appropriate style.
• Write a concise annotation that summarizes the central theme and scope of the book or article. (See Formatting your Annotated Bibliography to see what to included in your annotation).
• Write an introduction to your annotated bibliography: Define the topic, and the scope of your bibliography, whether it is meant to cover the whole range of opinion or just one viewpoint or aspect. Describe the scope of your bibliography, include whether it covers what you judge to be the best, or the most recent, or a broad sample of the available material on your topic.
• Review your AB and introduction, be sure that your introduction is based on on the citations you have selected.

A bibliography is a list of works (books, articles, films, etc.) on a particular topic. An annotated bibliography includes a paragraph following each citation that summarizes the work. An annotation can help the reader determine the value of each work on the topic and the contribution it might make to his own research. Abstracts are the purely descriptive summaries often found at the beginning of scholarly journal articles or in periodical indexes. Annotations are descriptive and/or critical; they expose the author's point of view, clarity and appropriateness of expression, and authority.

Elements of an Annotation

Sample elements of a critical annotated bibliography

Check with your instructor to determine what he/she wants to be included in annotations. In general, an annotation should inform the reader of the quality and relevance of the source. Annotations are detailed but succinct, typically about 150 words, and include:

• a brief summary (2-4 sentences) of the article, including the author’s name and what you think is the author’s primary point or thought;
• a description of the intended audience;
• how the article illuminates your bibliography topic;
• an evaluation of the source’s usefulness, reliability, strengths and weaknesses and its value for your research;
• how this specific article relates to another article in your bibliography

For more information, see:

• Annotated Bibliographies UMKC Libraries
• Preparing an Annotated Bibliography OWL at Purdue
• Descriptive
• Informative

There are different kinds of annotations, depending on what might be most important for your reader to learn about a source. Three common types of annotated bibliographies are Descriptive , Informative , and Critical .

Three Types of Annotations: Critical, Descriptive, and Informative

A Descriptive annotation may summarize:

• The main purpose or idea of the work
• The contents of the work
• The author’s conclusions
• The intended audience
• The author’s research methods
• Special features of the work such as illustrations, maps, and tables

This type of annotation seeks to answer the question, Does this source cover or address the topic I am researching?

An Informative annotation:

• Summarizes what the content, message, or argument of the source is
• Generally contains the hypothesis, methodology, main points, and conclusion or results
• Does not include any editorial or evaluative comments about such content

This type of annotation seeks to answer these types of questions, What are the author's main arguments? What conclusions did the author draw?

A Critical annotation includes value judgments or comments on the effectiveness of the work. In this context, critical means evaluative and may include both positive and negative comments. A critical annotation may contain the information found in a descriptive annotation and discuss some of the following features:

• The importance of the work’s contribution to the literature of the subject
• The author’s bias or tone
• The author’s qualifications for writing the work
• The accuracy of the information in the source
• Limitations or significant omissions
• The work’s contribution to the literature of the subject
• Comparison with other works on the topic

This type of annotation seeks to answer these types of questions:

• Is the author's presentation of the facts objective?
• Is the methodology sound? Is this source useful for my audience?
• Are the conclusions still valid in light of new research?
• What contribution does this make to the field?
• Does this source address all the relevant issues?

APA Annotated Bibliography Format

The American Psychological Association states that your instructor should set the guidelines for your annotated bibliography, but does ask that the list be formatted according to their standard reference page rules (see Section 9.51 of the  Publication Manual ). Since there are no set rules for creating one, you may be wondering how to create an annotated APA bibliography. If your teacher or professor requests one, don’t worry, here are our recommendations:

• Make sure you create your references according to APA’s guidelines. If you need some help, here’s a great  APA citation website , which shows how to create references for electronic sources. We also have a page on developing a reference for an  APA journal . Need other source types? Check out the other helpful pages on EasyBib.com.
• Annotations should be kept short and are usually not more than one paragraph.
• For more information on writing an annotation, visit the general  annotated bibliography guide .

Here’s a run-through of everything this page includes:

• Quick APA formatting guidelines

Annotation example

Visual example, using the easybib annotation tool, troubleshooting, quick  apa  formatting guidelines:.

• Use 1-inch page margins on all sides.
• The entire page should be double-spaced.
• Title your page, “Annotated Bibliography”. Center and bold it.
• Left-align references. If a reference runs over more than one line, any line(s) that comes after the first should be indented a ½ inch from the left margin.
• Organize your references alphabetically by the first word in the reference. (See further details in this  APA Reference Page  guide).
• Add the annotations on the line right after their corresponding reference.
• Indent annotations ½ inch from the left margin.
• Include a page number in the upper right corner; if this is a professional paper, it should be a running head.

For an annotated bibliography APA example, we’re using the same description as above. The only thing we’re going to change is the structure of the reference. For an APA bibliography, the reference needs to be an  APA citation , and the description can be formed the same way as above.

Here’s what the  APA book citation  for  The Elements of Eloquence: Secrets of the Perfect Turn of Phrase  looks like:

Forsyth, M. (2014).  The elements of eloquence: Secrets of the perfect turn of phrase.  Penguin Books.

The author, Mark Forsyth, examines the rhetorical devices used in the English language, analyzing the patterns and formats that create memorable quotes. He traces the history of rhetoric to the Ancient Greeks, and provides an abridged timeline, following their use and evolution through to modern day. The author also explores the broader subject of persuasion and maps out the role that the figures of rhetoric play in it. In all, he examines over thirty devices, dissecting notable passages and phrases from pop music, the plays of William Shakespeare, the Bible, and more to explore the figures of rhetoric at work within each of them. Thorough definitions accompany this examination of structure to demonstrate how these formulas have been used to generate famously memorable expressions as well as how to reproduce their effects.

The EasyBib citation generator has an annotation tool that can help you easily add your annotation to a citation.

• To do this, begin creating a citation in the EasyBib citation generator. Already have a citation on EasyBib.com? Go to the citation, open your citation options and select “Edit citation.”
• Once you get to the citation form (where you review found information), scroll to the bottom until you see the sections “More options.”
• Under that section, click on the “Add annotation” link to open the annotation box.
• Copy and paste your annotation into the box.
• Complete your citation.
• Your annotation will automatically be included and formatted with your citation. You can copy and paste directly into your paper!

Again, even though the APA style does not support the creation of bibliographies that include annotations, many schools and professors expect their students to include summaries or commentary alongside their citations in APA style.

Solution #1: How to write an annotation

Annotations are brief paragraph summaries of your source and may include details about how you plan to use the information in your paper, or the quality of information in your source. Take these steps:

• Read through the source.
• Identify the main thesis theme of the source then consider how you would summarize the article and its purpose in one sentence.
• Evaluate the source. Is the author(s) qualified? Is the source and its arguments credible? Well-written? Why or why not?
• How does the source relate to your paper?
• Write your annotation based on the above steps. Choose only the points that would most help you or your reader gain an understanding of the source and its significance.

Here are writing tips:

• Avoid describing every event, statistic, or detail that occurs in your source.
• Focus on details that are relevant to your topic or your paper. Help the reader understand why the source was selected and is importance.
• Think about how the information impacts your perspective, how it contributes to your topic, and the effect on your overall paper.

Annotated paragraph example:

Solution #2: How to correctly format an annotation with multiple paragraphs

• Indent the entire annotated paragraph at ½ of an inch. When done correctly, the left edge of the annotated paragraph will look entirely straight, as in the first example below.
• If there are multiple paragraphs, follow step one but use a second 0.5-inch indention on the second and following paragraphs.
• Avoid indenting the paragraph at 0.5 inch like a regular essay paragraph, as shown in the third example.

Single annotated paragraph example:

Multiple annotated paragraphs example:

In his novel, “A True Story of John Doe,” Samuel Smith outlines his life through the eyes of a fictional character. His recollection outlines the immigrant experience and demonstrates how modern life in England came to be.

          Chapters two and three outline the novelty of moving to a new location by describing the eventual progression to culture shock. Smith describes life as beautiful and wonderous in chapter two by emphasizing sensory experiences. However, in chapter three, he slowly gains awareness of the differences between his current and previous lives and of how the locals treat him. Smith nullifies the sensory experiences and, instead, focuses on the depth of the human emotion. I intend to use this source to compare to my own experience as an immigrant.

To create an annotated APA bibliography, follow the below recommendations:

• Order your reference entries in alphabetical order similar to how you would order entries in the reference list.
• If you want to add an annotation to an entry, add it as a new paragraph below the reference entry. The entire annotation is indented 0.5 inches from the left margin.

For example:

Lim, L. (2014). Ideology, rationality and reproduction in education: A critical discourse analysis. Discourse: Studies in the Cultural Politics of Education, 35 (1), 61–76. https://doi.org/10.1080/01596306.2012.739467 Lim focuses on issues of power and ideology dominant in curricular discourses of rationality to study a discourse analysis of the goals of one of the most important curricula in the teaching of thinking. He proves that political and class commitments are reproduced in the forms of thinking that are valued in societies. Through his research, Lim asserts that such curricula engage in creating our understanding of what thinking and rationality are.

To format an annotated bibliography in APA, follow the recommendations given below:

• Set the left, right, top, and bottom margins as 1 inch.
• Use double-line spacing.
• Title the page “Annotated Bibliography.” Set it in bold.
• The title should be aligned to the center of the page.
• As you format reference entries, left-align all references in the annotated bibliography section. If any entry runs over more than a line, indent the subsequent lines 0.5 inches from the left margin.
• Arrange all reference entries alphabetically according to the surname of the authors.
• Provide your annotations below the reference entry for which you want to give your annotation. Indent annotations 0.5 inches from the left margin.

Write an Annotated Bibliography

What is an annotated bibliography?

It is a list of citations for various books, articles, and other sources on a topic. 

An annotation is a short summary and/or critical evaluation of a source.

Annotated bibliographies answer the question: "What would be the most relevant, most useful, or most up-to-date sources for this topic?"

 Annotated bibliographies can be part of a larger research project, or can be a stand-alone report in itself. 

Annotation versus abstracts 

An abstract is a paragraph at the beginning of the paper that discusses the main point of the original work. They typically do not include evaluation comments. 

Annotations can either be descriptive or evaluative. The annotated bibliography looks like a works cited page but includes an annotation after each source cited. 

Types of Annotations: 

Descriptive Annotations: Focuses on description. Describes the source by answering the following questions. 

Who wrote the document?

What does the document discuss?

When and where was the document written? 

Why was the document produced?

How was it provided to the public?

Evaluative Annotations: Focuses on description and evaluation. Includes a summary and critically assess the work for accuracy, relevance, and quality. 

Evaluative annotations help you learn about your topic, develop a thesis statement, decide if a specific source will be useful for your assignment, and determine if there is enough valid information available to complete your project.

What does the annotation include?

Depending on your assignment and style guide, annotations may include some or all of the following information. 

• Should be no more than 150 words or 4 to 6 sentences long. 
• What is the main focus or purpose of the work?
• Who is the intended audience?
• ​How useful or relevant was the article to your topic?
• Was there any unique features that useful to you?
• What is the background and credibility of the author?
• What are any conclusions or observations that your reached about the article?

Which citation style to use?

There are many styles manuals with specific instructions on how to format your annotated bibliography. This largely depends on what your instructor prefers or your subject discipline. Check out our citation guides for more information. 

Additional Information

Why doesn't APA have an official APA-approved format for annotated bibliographies?

Always consult your instructor about the format of an annotated bibliography for your class assignments. These guides provide you with examples of various styles for annotated bibliographies and they may not be in the format required by your instructor. 

Citation Examples and Annotations

Book Citation with Descriptive Annotation

Liroff, R. A., & G. G. Davis. (1981). Protecting open space: Land use control in the Adirondack Park. Cambridge, MA: Ballinger.

This book describes the implementation of regional planning and land use regulation in the Adirondack Park in upstate New York. The authors provide program evaluations of the Adirondack Park Agency’s regulatory and local planning assistance programs.

Journal Article Citation with Evaluative Annotation

Gottlieb, P. D. (1995). The “golden egg” as a natural resource: Toward a normative theory of growth management. Society and Natural Resources, 8, (5): 49-56.

This article explains the dilemma faced by North American suburbs, which demand both preservation of local amenities (to protect quality of life) and physical development (to expand the tax base). Growth management has been proposed as a policy solution to this dilemma. An analogy is made between this approach and resource economics. The author concludes that the growth management debate raises legitimate issues of sustainability and efficiency.

Book Citation

Lee, Seok-hoon, Yong-pil Kim, Nigel Hemmington, and Deok-kyun Yun. “Competitive Service Quality Improvement (CSQI): A Case Study in the Fast-Food Industry.” Food Service Technology 4 (2004): 75-84.

In this highly technical paper, three industrial engineering professors in Korea and one services management professor in the UK discuss the mathematical limitations of the popular SERVQUAL scales. Significantly, they also aim to measure service quality in the fast-food industry, a neglected area of study. Unfortunately, the paper’s sophisticated analytical methods make it inaccessible to all but the most expert of researchers.

Battle, Ken. “Child Poverty: The Evolution and Impact of Child Benefits.”  A Question of Commitment: Children's Rights in Canada . Ed. Katherine Covell and R.Brian Howe. Waterloo, ON: Wilfrid Laurier University Press. 2007. 21-44.

             Ken Battle draws on a close study of government documents, as well as his own research as an extensively-published policy analyst, to explain Canadian child benefit programs.  He outlines some fundamental assumptions supporting the belief that all society members should contribute to the upbringing of children.  His comparison of child poverty rates in a number of countries is a useful wake-up to anyone assuming Canadian society is doing a good job of protecting children.  Battle pays particular attention to the National Child Benefit (NCB), arguing that it did not deserve to be criticized by politicians and journalists.  He outlines the NCB’s development, costs, and benefits, and laments that the Conservative government scaled it back in favour of the inferior Universal Child Care Benefit (UCCB).  However, he relies too heavily on his own work; he is the sole or primary author of almost half the sources in his bibliography.  He could make this work stronger by drawing from others' perspectives and analyses.  However, Battle does offer a valuable source for this essay, because the chapter provides a concise overview of government-funded assistance currently available to parents.  This offers context for analyzing the scope and financial reality of child poverty in Canada.

Journal Article Example

  Kerr, Don and Roderic Beaujot. “Child Poverty and Family Structure in Canada, 1981-1997.”  Journal of Comparative Family Studies  34.3 (2003): 321-335.

             Sociology professors Kerr and Beaujot analyze the demographics of impoverished families.  Drawing on data from Canada’s annual Survey of Consumer Finances, the authors consider whether each family had one or two parents, the age of single parents, and the number of children in each household.  They analyze child poverty rates in light of both these demographic factors and larger economic issues.  Kerr and Beaujot use this data to argue that.
