How to write an annotated bibliography

What is an annotated bibliography.

An annotated bibliography or annotated bib is a bibliography (a list of books or other works) that includes descriptive and evaluative comments about the sources cited in your paper. These comments are also known as annotations .

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 professor has requested for the assignment. Some common citation styles include APA , MLA , and Chicago . For more information, see the Style Guides page.

Generally, an annotation is approximately 100-300 words in length (one paragraph). However, your professor may have different expectations so it is recommended that you clarify the assignment guidelines.

An annotation may include the following information:

• A brief summary of the source
• The source’s strengths and weaknesses
• Its conclusions
• Why the source is relevant in your field of study
• Its relationships to other studies in the field
• An evaluation of the research methodology (if applicable)
• Information about the author’s background
• Your personal conclusions about the source

MLA style format (8th ed.)

Hanging Indents are required for citations in the bibliography, as shown below. That is, the first line of the citation starts at the left margin, and subsequent lines are indented 4 spaces.  The bibliography is double-spaced, both within the citation and between them. The annotation appends the entry unless complete sentences are used, then a line space is added and the annotation begins with a paragraph indent, as shown in the example below.

Lozier, Jeffrey D., et al. "Predicting the Distribution of Sasquatch in Western North America: Anything Goes with Ecological Niche Modelling." Journal of Biogeography , vol. 36, no.9, 2009, pp. 1623-1627. JSTOR, http://www.jstor.org/stable/40305930. Accessed 14 June 2016.    This paper critiques the use of Ecological Niche Models (ENM) and species distribution by performing a tongue-in-cheek examination of the distribution of the fictional Sasquatch, based on reports from an online Bigfoot archive.Lozier's paper powerfully demonstrates the issues faced by ENM, when reports come from non-specialists, and highlights key problems with sourcing data from unmediated online environments. The author neglects to compare the reliability of the many wildlife databases with the single Bigfoot database, as well as other key issues; however in closing, the paper briefly mentions that many issues lie outside the scope of the short article. Lozier's paper advises professionals in fields using ENM to carefully assess the source of the data on which the model is based and concludes that the distribution of rare species in particular is often over-reported to misidentification.

APA style format (7th ed.)

Refer to Section 9.51, p. 307 and Figure 9.3, p. 308 in the Publication Manual of the American Psychological Association, 7th ed. [ print ] for detailed information on annotated bibliographies.

The following are general guidelines. Check with your instructor for

References follow the same alphabetical order as entries in a reference list [Section 9.43-9.44, p. 303]. The annotation is a new paragraph below its reference entry and follows block quotation format [Section 8.27, pp. 272-273]. Should the annotation have multiple paragraphs, the first line of the second and subsequent paragraphs are indented an additional 0.5in.

D’Elia, G., Jorgensen, C., Woelfel, J., & Rodger, E. J. (2002). The impact of the Internet on public library use: An analysis of the current consumer market for library and Internet services. Journal of the American Society for Information Science and Technology, 53 (10), 808-820. https://doi.org/10.1002/asi.10102 In this study, the researchers examined if the Internet had affected public library usage in the United States. This study is distinct because its researchers surveyed library nonusers as well as   users. The major finding was that 75.2% of people who used the Internet also used the public library. However, the researchers surveyed only 3000 individuals in a population of millions; therefore, these results may not be statistically significant. However, this study is relevant because it provides future researchers with a methodology for determining the impact of the Internet on public library usage.

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.

Annotated Bibliography

What is an annotated bibliography.

An annotated bibliography provides an overview or a brief account of the available research on a given topic. It is a list of research sources that takes the form of a citation for each source, followed by an annotation - a short paragraph sumarising and evaluating the source. An annotated bibliography may be a stand-alone assignment or a component of a larger assignment. 

Purpose of an annotated bibliography

When set as an assignment, an annotated bibliography allows you to get acquainted with the material available on a particular topic.

Depending on your specific assignment, an annotated bibliography might:

• review the literature of a particular subject;
• demonstrate the quality and depth of reading that you have done;
• exemplify the scope of sources available—such as journals, books, web sites and magazine articles;
• highlight sources that may be of interest to other readers and researchers;
• explore and organise sources for further research.

What does an annotated bibliography look like?

Each entry in an annotated biliography has two components: 

• a bibliographic citation followed by 
• a short paragraph (an annotation) that includes concise descriptions and evaluations of each source. 

The annotation usually contains a brief summary of content and a short analysis or evaluation. Depending on your assignment you may be asked to summarise, reflect on, critique, evaluate or analyse each source. While an annotation can be as brief as one sentence, a paragraph is more usual.  An example is provided below.

As with a normal reference list or bibliography, an annotated bibliography is usually arranged alphabetically according to the author’s last name.

An annotated bibliography summary should be about 100 - 200 words per citation—check with your lecturer/tutor as this may vary between faculties and assessments. Please also check with your lecturer about the elements each annotation should include.

Steps to writing an annotated bibliography

• Choose your sources - locate and record citations to sources of research that may contain useful information and ideas on your topic.
• Review the items that you’ve collected in your search.
• Write the citation using the correct style.
• Write the annotation. 

Questions to consider when selecting sources

The sources for your annotated bibliography should be carefully selected. Start by reading abstracts or skimming to help you identify and select relevant sources. Also keep in mind that, while annotated bibliographies are often ‘stand alone’ assignments, they can also be preliminary research about a particular topic or issue, and further research or a longer literature review may follow. Try to choose sources which together will present a comprehensive review of the topic.

Keep the following questions in mind to help clarify your choices

• What topic/ problem am I investigating?
• What question(s) am I exploring? (Identify the aim of your literature research). 
• What kind of material am I looking at and why? Am I looking for journal articles, reports, policies or primary data? 
• Am I being judicious in my selection of sources? Does each one relate to my research topic and assignment requirements?
• Have I selected a range of sources? Choose those sources that provide a variety of perspectives on your topic
• What are the essential or key works about my topic? Am I finding them? Are the sources valuable or often referred to in other sources?

Surveying the sources

Take notes on your selected texts as you read. Pay attention to:

• the author’s theoretical approach.
• which parts of the topic are covered.
• main points or findings on the topic.
• the author’s position or argument. 

Evaluate and ask questions as you read

Record evaluations in your notes and consider:

• How, and how effectively, does this source address the topic?
• Does it cover the topic thoroughly or only one aspect of it?
• Do the research methods seem appropriate?
• Does the argument seem reasonable?
• Where does it stand in relation to other studies? Agree with or contradict?

How should I write the annotations?

• Each annotation should be concise. Do not write too much—annotations should not extend beyond one paragraph (unless assignment guidelines say otherwise). 
• The summary should be a brief outline of argument(s) and main ideas. Only mention details that are significant or relevant, and only when necessary. 
• Any information apparent in the title of thesourcel can be omitted from the annotation.
• Background materials and references to previous work by the same author usually are not included. As you are addressing one text at a time, there is no need to cross reference or use in-text citations to support your annotation.
• Find out what referencing style you need to use for the bibliographic citations, and use it consistently.
• In-text citations would usually only be necessary for quotations or to draw attention to information from specific pages.
• Unless otherwise stipulated, you should write in full sentences using academic vocabulary.

Contents of an annotated bibliography

An annotation may contain all or part of the following elements depending on the word limit and the content of the sources you are examining.

• Provide the full bibliographic citation.
• Indicate the background of the author(s).
• Indicate the content or scope of the text.
• Outline the main argument.
• Indicate the intended audience.
• Identify the research methods if applicable.
• Identify any conclusions made by the author/s.
• Discuss the reliability of the text.
• Highlight any special features of the text that were unique or helpful e.g. charts, graphs etc.
• Discuss the relevance or usefulness of the text for your research.
• Point out in what way the text relates to themes or concepts in your course.
• State the strengths and limitations of the text.
• Present your view or reaction to the text.

Sample annotation 

The citation goes first and is followed by the annotation. Make sure that you follow your faculty’s preferred citation style. The summary needs to be concise. Please note the following example is entirely fictitious.

In the sample annotation below, each element is numbered (see Key).

Writing an annotated bibliography

An annotated bibliography provides a brief account of the available research on a given topic. Find out how to select resources, what to include, and which writing style to use.

What is an annotated bibliography?

An annotated bibliography reviews the research published on your problem of study. Unlike a literature review, articles are reviewed separately with a full citation, brief summary of their content and a statement on how or why they apply to your research. It is a list of citations, each followed by a short paragraph, of 150 – 200 words, reviewing each source. Depending on your assignment, in this paragraph you may reflect on, summarise, critique, evaluate or analyse the source.

An annotated bibliography may be a component of a larger assignment or it may be a standalone document.

Why write an annotated bibliography?

Depending on your specific assessment, you may be asked to create an annotated bibliography for the following reasons:

• To familiarise yourself with the material available on a particular topic
• To demonstrate the quality and depth of reading that you have done
• To identify range of sources available on your topic
• To highlight sources that may be of interest to other readers and researchers
• To explore and organise sources for further research, e.g. as the first step toward a literature review

What kind of resources should be studied?

Review recent academic materials such as academic books and peer reviewed journals. Textbooks and web pages are generally not appropriate as the content may be either too broad or unreliable.

The sources you choose will depend on your topic. Choose sources which most closely answer a clearly defined question or problem from a balanced range of approaches, not only those which confirm your current beliefs. Also, include any references which are considered central to your topic.

How to create an annotated bibliography

These are good places to start:

• Your lecture notes / references given in class
• The Library Guide for your subject
• The subject liaison librarian

First, read abstracts or academic book reviews to help you select studies most relevant to your problem, then select the most suitable from those to read in full.  Take notes on your selected texts as you read. Pay attention to:

• the author’s theoretical approach.
• which parts of the topic are covered in this paper.
• main points or findings on the topic.
• the author’s position or argument.

Record evaluations in your notes; your bibliography should not merely be a catalogue but present your own informed position on the texts and the topic as a whole.

• How well does this text address your topic?
• Does it cover the topic thoroughly or only one aspect of it?
• Do the research methods seem appropriate and does the argument stand up to scrutiny?
• Does it agree with or contradict other studies?
• List texts in alphabetical order using citation conventions for a reference list.
• Create an annotation under each citation: a paragraph summarising each text and explaining how the text applies to your research question or problem. e.g. What aspect of your question/ problem does it address?  How fully? Does it provide background information/ theory / useful results? How strong is the evidence?  What are its limitations in answering your research question?

Find out what citation style you need to use, such as APA, Vancouver, MLA. Department style guides or detailed assignment briefs often provide information on this. Details of how to cite are explained in re:cite.

Write in complete sentences to create a cohesive ‘snapshot’ of the text and its contribution to your research. Be brief and selective; aim to outline the text in less than 200 words.

An annotation may contain all or part of the following elements depending on the word limit and the content of the sources you are examining:

You might include:

• the background of the author(s)
• the content or scope of the text
• the main argument
• the intended audience
• the research methods (if applicable)
• any conclusions made by the author/s
• comments on the reliability of the text
• any special features of the text that were helpful (charts, graphs etc.)
• the relevance or usefulness of the text for your research
• the strengths and limitations of the text

Below is a sample annotation (APA). The superscript numbers at the end of the sentence explain the features or elements covered.

Scoffer, J., Treet, M., Nibbell, A., Tayste, C., & Snacker, A. (2017). Visual priming for chocolate increases chocolate consumption–an attention bias modification study. Journal of Healthy Eating, 38(1), 176-183. 1

The study examines the effect of attention priming on subsequent chocolate consumption within a University context 2 . 120 female subjects were primed with presentations of pictures either of shoes or chocolate, then participated in a chocolate search 3 . Findings indicated that the group primed with visual stimuli of chocolate showed significantly higher persistence in the chocolate searching task, consuming on average greater amounts of chocolate 4 . The authors contend that attention to food stimuli could increase risk of weight gain for many individuals 5 . By demonstrating the role of visual attention in subsequent food seeking behaviour and quantity consumed, this study provides evidence that such visual stimuli as web-based or billboard-based advertisements containing images of food may present a health risk to many individuals 6 . Limitations of the study include the lack of a true control since no non-primed condition was included. Another limitation is the use of a highly prized foodstuff, which limits the application of the findings to more everyday foods less closely related to reward 7 . However, the positive finding on the role of visual priming in food seeking and consumption provides useful support for the argument in my research that visual advertising contributes to weight problems, particularly in an obesogenic environment 8 .

4 Summary of findings

5 Author’s main contention/ argument

6 Usefulness for your research

7 Limitations for your study

8 Reflection on how this work informs your research and how it will be applied.

As you research, keep in mind that annotated bibliographies are often preliminary research for a single, cohesive literature review about a situation or problem. Try to choose sources which together will present a comprehensive review of the issue under study.

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?

How to write an annotated bibliography

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.

Examples for a book chapter

Carson, R. (1962). The obligation to endure. In Silent spring (pp. 5-13). Boston: Houghton Mifflin. Carson talks about the overuse of chemicals to kill insects and other pests that invade and harm the nation's environment and agriculture. She thinks that chemicals that people once thought would control disease in plants are now going to cause another worse kind of disease in humans. She uses some history and current realities to back up her points.

An evaluative annotation (again, APA format): Carson, R. (1962). The obligation to endure. In Silent spring (pp. 5-13). Boston: Houghton Mifflin. Carson, in this chapter from Silent Spring, claims that chemical pollution, especially in the form of pesticides, is "the most alarming of all man's assaults upon the environment" (152). Modern science's creation of new chemicals (almost five hundred a day) and their subsequent use--two hundred of them alone used to kill pests of all kinds--have begun to alter the biological environment irrevocably, so that nuclear warfare is no longer the most certain means of wiping out life on the planet. Instead, the real killer becomes the many poisons we use to wipe out pests. These already are causing and will cause ultimately all kinds of genetic alterations in plant and animal life that will bring about the end of life as we know it. Carson does not advocate a complete end to chemical pest control, but she does insist that chemicals should be used only after they have been thoroughly investigated, tested, and understood. And then they should be used only by those who understand how to use them and their potential for both benefit and harm.

The second annotation is longer than the first, but it is also evaluative. A descriptive annotation is simply a list of topics an author talks about, while an evaluative annotation states conclusively what the author thought about, how he/she thought about it, and what it finally meant for the piece of writing he/she produced. Ask your instructor how you should write your annotations.

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

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.

Learning Outcomes

By the end of this section, you will be able to:

• Integrate your ideas with ideas from related sources.
• Locate, compile, and evaluate primary, secondary, and tertiary research materials related to your topic.

A bibliography is a list of the sources you use when doing research for a project or composition. Named for the Greek terms biblion , meaning “book,” and graphos , meaning “something written,” bibliographies today compile more than just books. Often they include academic journal articles, periodicals, websites, and multimedia texts such as videos. A bibliography alone, at the end of a research work, also may be labeled “References” or “Works Cited,” depending on the citation style you are using. The bibliography lists information about each source, including author, title, publisher, and publication date. Each set of source information, or each individual entry, listed in the bibliography or noted within the body of the composition is called a citation .

Bibliographies include formal documentation entries that serve several purposes:

• They help you organize your own research on a topic and narrow your topic, thesis, or argument.
• They help you build knowledge.
• They strengthen your arguments by offering proof that your research comes from trustworthy sources.
• They enable readers to do more research on the topic.
• They create a community of researchers, thus adding to the ongoing conversation on the research topic.
• They give credit to authors and sources from which you draw and support your ideas.

Annotated bibliography expand on typical bibliographies by including information beyond the basic citation information and commentary on the source. Although they present each formal documentation entry as it would appear in a source list such as a works cited page, an annotated bibliography includes two types of additional information. First, following the documentation entry is a short description of the work, including information about its authors and how it was or can be used in a research project. Second is an evaluation of the work’s validity, reliability, and/or bias. The purpose of the annotation is to summarize, assess, and reflect on the source. Annotations can be both explanatory and analytical, helping readers understand the research you used to formulate your argument. An annotated bibliography can also help you demonstrate that you have read the sources you will potentially cite in your work. It is a tool to assist in the gathering of these sources and serves as a repository. You won’t necessarily use all the sources cited in your annotated bibliography in your final work, but gathering, evaluating, and documenting these sources is an integral part of the research process.

Compiling Sources

Research projects and compositions, particularly argumentative or position texts, require you to collect sources, devise a thesis, and then support that thesis through analysis of the evidence, including sources, you have compiled. With access to the Internet and an academic library, you will rarely encounter a shortage of sources for any given topic or argument. The real challenge may be sorting through all the available sources and determining which will be useful.

The first step in completing an annotated bibliography is to locate and compile sources to use in your research project. At the beginning, you do not need to be highly selective in this process, as you may not ultimately use every source. Therefore, gather any materials—including books, websites, professional journals, periodicals, and documents—that you think may contain valuable ideas about your topic. But where do you find sources that relate to your argument? And how do you choose which sources to use? This section will help you answer those questions and choose sources that will both enhance and challenge your claim, allowing you to confront contradictory evidence and synthesize ideas, or combine ideas from various sources, to produce a well-constructed original argument. See Research Process: Accessing and Recording Information for more information about sources and synthesizing information.

Primary, Secondary, and Tertiary Sources

In your research, you likely will use three types of sources: primary, secondary, and tertiary. During any research project, your use of these sources will depend on your topic, your thesis, and, ultimately, how you intend to use them. In all likelihood, you will need to seek out all three.

Primary Sources

Primary sources allow you to create your own analysis with the appropriate rhetorical approach. In the humanities disciplines, primary sources include original documents, data, images, and other compositions that provide a firsthand account of an event or a time in history. Typically, primary sources are created close in time to the event or period they represent and may include journal or diary entries, newspaper articles, government records, photographs, artworks, maps, speeches, films, and interviews. In scientific disciplines, primary sources provide information such as scientific discoveries, raw data, experimental and research results, and clinical trial findings. They may include published studies, scientific journal articles, and proceedings of meeting or conferences.

Primary sources also can include student-conducted interviews and surveys. Other primary sources may be found on websites such as the Library of Congress , the Historical Text Archive , government websites, and article databases. In all academic areas, primary sources are fact based, not interpretive. That is, they may be commenting on or interpreting something else, but they themselves are the source. For example, an article written during the 1840s condemning the practice of enslavement may interpret events occurring then, but it is a primary source document of its time.

Secondary Sources

Secondary sources , unlike primary sources, are interpretive. They often provide a secondhand account of an event or research results, analyze or clarify primary sources and scientific discoveries, or interpret a creative work. These sources are important for supporting or challenging your argument, addressing counterarguments, and synthesizing ideas. Secondary sources in the humanities disciplines include biographies, literary criticism, and reviews of the fine arts, among other sources. In the scientific disciplines, secondary sources encompass analyses of scientific studies or clinical trials, reviews of experimental results, and publications about the significance of studies or experiments. In some instances, the same item can serve as both a primary and a secondary source, depending on how it is used. For example, a journal article in which the author analyzes the impact of a clinical trial would serve as a secondary source. But if you instead count the number of journal articles that feature reports on a particular clinical trial, you might use them as primary sources because they would then serve as data points.

Table 14.1 provides examples of how primary and secondary sources often relate to one another.

Tertiary Sources

In addition to primary and secondary sources, you can use a tertiary source to summarize or digest information from primary and/or secondary sources. Because tertiary sources often condense information, they usually do not provide enough information on their own to support claims. However, they often contain a variety of citations that can help you identify and locate valuable primary and secondary sources. Researchers often use tertiary sources to find general, historical, or background information as well as a broad overview of a topic. Tertiary sources frequently placed in the secondary-source category include reference materials such as encyclopedias, textbooks, manuals, digests, and bibliographies. For more discussion on sources, see The Research Process: Where to Look for Existing Sources .

Authoritative Sources

Not all sources are created equally. You likely know already that you must vet sources—especially those you find on the Internet—for legitimacy, validity, and the presence of bias. For example, you probably know that the website Wikipedia is not considered a trustworthy source because it is open to user editing. This accessibility means the site’s authority cannot be established and, therefore, the source cannot effectively support or refute a claim you are attempting to make, though you can use it at times to point you to reliable sources. While so-called bad sources may be easy to spot, researchers may have more difficulty discriminating between sources that are authoritative and those that pose concerns. In fact, you may encounter a general hierarchy of sources in your compilation. Understanding this hierarchy can help you identify which sources to use and how to use them in your research.

Peer-Reviewed Academic Publications

This first tier of sources—the gold standard of research—includes academic literature, which consists of textbooks, essays, journals, articles, reports, and scholarly books. As scholarly works, these sources usually provide strong evidence for an author’s claims by reflecting rigorous research and scrutiny by experts in the field. These types of sources are most often published, sponsored, or supported by academic institutions, often a university or an academic association such as the Modern Language Association (MLA) . Such associations exist to encourage research and collaboration within their discipline, mostly through publications and conferences. To be published, academic works must pass through a rigorous process called peer review , in which scholars in the field evaluate it anonymously. You can find peer-reviewed academic sources in library catalogs, in article databases, and through Google Scholar online. Sometimes these sources require a subscription to access, but students often receive access through their school.

Academic articles, particularly in the social and other sciences, generally have most or all of the following sections, a structure you might recognize if you have written lab reports in science classes:

• Abstract . This short summary covers the purpose, methods, and findings of the paper. It may discuss briefly the implications or significance of the research.
• Introduction . The main part of the paper begins with an introduction that presents the issue or main idea addressed by the research, establishes its importance, and poses the author’s thesis.
• Review . Next comes an overview of previous academic research related to the topic, including a synthesis that makes a case for why the research is important and necessary.
• Data and Methods . The main part of the original research begins with a description of the data and methods used, including what data or information the author collected and how the author used it.
• Results . Data and methods are followed by results, detailing the significant findings from the experiment or research.
• Conclusion . In the conclusion, the author discusses the results in the context of the bigger picture, explaining the author’s position on how these results relate to the earlier review of literature and their significance in the broad scope of the topic. The author also may propose future research needs or point out unanswered questions.
• Works Cited or References . The paper ends with a list of all sources the author used in the research, including the review of literature. This often-overlooked portion of the composition is critical in evaluating the credibility of any paper that involves research.

Credible Nonacademic Sources

These sources, including articles, books, and reports, are second in authority only to peer-reviewed academic publications. Credible nonacademic sources are often about current events or discoveries not yet reviewed in academic circles and often provide a wider-ranging outlook on your topic. Peer-reviewed texts tend to be narrow and specific, whereas nonacademic texts from well-researched sources are often more accessible and can offer a broader perspective. These three major categories generally provide quality sources:

• Information, white papers, and reports from government and international agencies such as the United Nations , the World Health Organization , and the United States government
• Longer articles and reports from major newspapers, broadcast media, and magazines that are well regarded in academic circles, including the New York Times , the Wall Street Journal , the BBC, and the Economist
• Nonacademic books written by authors with expertise and credentials, who support their ideas with well-sourced information

To find nonacademic sources, search for .gov or .org sites related to your topic. A word of caution, however: know that sources ending in .org are often advocacy sites and, consequently, inherently biased toward whatever cause they are advocating. You also can look at academic article databases and search articles from major newspapers and magazines, both of which can be found online.

Short Informational Texts from Credible Websites and Periodicals

The next most authoritative sources are shorter newspaper articles or other pieces on credible websites. These articles tend to be limited in scope, as their authors report on a single issue or event. Although they do not often provide in-depth analysis, they can be a source of credible facts to support your argument. Alternatively, they can point you in the direction of more detailed or rigorous sources that will enhance your research by tracing the original texts or sources on which the articles are based. Usually, you can find these sources through Internet searches, but sometimes you may have difficulty determining their credibility.

Judging Credibility

To judge credibility, begin by looking for the author or organization publishing the information. Most periodical compositions contain a short “About the Author” blurb at the beginning or end of the article and often include a link to the author’s credentials or to more information about them. Using this information, you can begin to determine their expertise and, potentially, any agenda the author or organization may have. For example, expect a piece discussing side effects of medical marijuana written by a doctor to present more expertise than the same piece written by a political lobbyist. You also can determine whether bias is present; for example, the organization may promote a particular way of thinking or have an agenda that will influence the content and language of the composition. In general, look for articles written with neutral expertise.

The CRAAP Test

You may find the CRAAP test a helpful and easy-to-remember tool for testing credibility. This checklist provides you with a method for evaluating any source for both reliability and credibility. CRAAP stands for Currency, Relevance, Authority, Accuracy, and Purpose. The CRAAP test, as shown in Table 14.2 , includes questions that can be asked of any source.

Sources with Clear Bias or Unclear Authority

The final type of source encompasses nearly everything else. Although they cannot be considered credible or valid to support your argument or claims, these sources are not necessarily useless. Especially when you are compiling sources at the beginning of a project, those with clear bias or unclear authority can be useful as you explore all facets of a topic, including positions within an argument. These sources also can help you identify topics on which to base your search terms and can even point you toward more credible sources.

Locating Sources

Academic article databases are the best starting places for finding sources. There are too many databases to cover them all in this chapter, but you would be wise to familiarize yourself with those to which you have access through your school or program. For further information on databases, see The Research Process: Where to Look for Existing Sources . In the long run, this knowledge will save you a good deal of time and a possible headache.

You will want to start with your college library website, which includes access to sources paid for by your institution. As a student, you should be able to access these quickly and easily. Another popular and wide-ranging database is Google Scholar . Google Scholar is helpful for finding sources across a wide range of topics. One drawback, however, is that it catalogues nearly all disciplines, so the results can be vast and unfocused. Therefore, when using Google Scholar, be as specific as possible, and add your academic discipline as a keyword. For example, when searching for information on climate change, add the keyword “environment” or “politics” depending on your research angle; otherwise, the results will include all disciplines and potentially bury the articles you seek. Google Scholar also has a feature labeled “Cited by,” which shows you other papers that cite the article in their review of literature relate to the topic. Writing Process: Informing and Analyzing contains more information about focusing your searches. Like clues to a mystery, one search can lead you to a wealth of related articles.

When you are able to identify potential sources by reading their abstracts or using Google Scholar, you may at times land on a publisher’s website that requires you to pay to read the full article. When you find yourself in a situation such as this, record information about the article—author(s), article title, journal title, publication date. It is likely that you will be able to use your school’s database to access the article. For information about other databases, consult The Research Process: Where to Look for Existing Sources .

Just as writing is recursive , requiring you to go back and forth between different stages of the process, you will likely return to your annotated bibliography at different points. You may begin by looking for sources related to your topic, or you may choose or narrow your topic after an initial database search for sources. If your project has a variety of possible topics, you may even start with a current issue of a leading journal in the field, find an article that interests you, and use that article to shape your topic selection. As a bonus, you will have your first reputable source. Later, as you refine your thesis, reasoning, and evidence, you may find yourself returning to your search for sources. Consider this hypothetical situation: You are developing an argument that examines the risk factors of childhood trauma that surface in later life. As you analyze the data from your sources, it occurs to you to find out whether any documented correlation exists between early trauma and resilience. So you return to Google Scholar and your university’s academic database to find more research based on this idea in order to revise your analysis by adding the new viewpoint.

One difficulty may be homing in on the keywords that will lead you to the sources you need. At this point, sources from the last two categories discussed may come into play: short pieces from credible websites and newspapers and other texts with clear bias or unclear authority. Less credible sources may lead you to better ones, particularly if you can identify the keywords used in them and then apply those keywords within academic databases. For more on developing useful keywords, consult The Research Process: Where to Look for Existing Sources .

Boolean Operators

Keyword searches can become frustrating, either yielding so much information that it seems impossible to sort through or narrowing the search so much that you miss important potential sources. One way to remedy this situation is to become familiar with Boolean operators , the basis of mathematical sets and database logic. Rather than searching with natural language only, you can use these operators to focus your search. The three basic Boolean operators are AND , OR , and NOT . Using these operators helps you search by linking necessary information, excluding irrelevant information, and focusing information. For example, if you have some pieces of information from tertiary sources, you may be able to use Boolean operators to find additional useful sources. A search string such as artificial intelligence (title) AND Buiten (author) AND 2019 (year) can yield the exact journal source you need. Here is a brief review of how to use the three operators:

• Use AND to narrow search results and tell the database to include all search terms in finding sources. If you want to find sources that include all of the search terms entered, use the AND operator. In Figure 14.11 , the darkest blue triangular section in the center of the Venn diagram represents the result set for this search, including all three terms. In many databases, including Google, AND is implied between each word. To exclude AND, use quotation marks. For example, Google would translate the search term ethics artificial intelligence as ethics AND artificial AND intelligence . To make your phrases more specific, use the AND operator combined with quotation marks: “ethics” AND “artificial intelligence” .
• Use OR to connect two or more similar concepts and broaden your results, telling the search engine that any of your search terms can appear in the results it gives you. The Boolean operator OR is represented by Figure 14.12 . Using the OR operator gives you a very large set of results.
• Use NOT to exclude results from a search. This operator can help you narrow your search, telling the search engine to ignore names or words you do not want included in your results. For example, if you know you don’t want self-driving cars in your search results, you might search for “artificial intelligence” NOT “self-driving cars” .

Choosing Sources

Choosing sources to include in your annotated bibliography may seem overwhelming. However, if you can find a few good academic articles as a starting point, use them to guide your research. Academic articles are efficient, scrutinized by experts in their fields, and organized in ways that aid readers in identifying key findings that relate to their argument. The following tips will help you choose solid sources to guide your research:

• Look for relevant scholarly articles. Even the briefest Google search can yield an overwhelming amount of content. Sift through it by looking first through academic databases to find high-quality sources relevant to your research.
• Read abstracts. As you sift through scholarly articles, you can get a good idea of what each one is about by reading the abstract. It includes the findings and will show you in about 100 words whether the paper holds relevance to your research.
• Skim. Once you have determined that an article may be useful, skim each section to glean the information you need. Closer and more extensive reading can come later as you develop and support your argument.
• Avoid getting bogged down in technical information or industry-specific jargon. The benefit of reading peer-reviewed research is that you know the reviewers have determined it to be solidly constructed. Therefore, even if you don’t understand some portions completely, you can still feel confident about using relevant information from the article.
• Work smarter by using the research provided. Once you have identified an article that is helpful to your research, use it to find more like it. Search for other publications by the authors; researchers often spend much of their careers researching one overarching topic or theme. Use the review of literature to identify related articles that may add to your research. You can also use the article’s bibliography to find additional sources. Or reverse engineer the process: use article databases to find other articles that cite the article in their literature reviews.
