Stem Cell Research: An Annotated Bibliography
Holland, Suzanne. The Human Embryonic Stem Cell Debate: Science, Ethics, and Public Policy. Boston: MIT P, 2001.
This is the annotation of the above source, which is formatted according to MLA 2016 (8th ed.) guidelines for the bibliographic information listed above. If one were really writing an annotation for this source, one would offer a brief summary of what this book says about stem cell research.
After a brief summary, it would be appropriate to assess this source and offer some criticisms of it. Does it seem like a reliable and current source? Why? Is the research biased or objective? Are the facts well documented? Who is the author? Is she qualified in this subject? Is this source scholarly, popular, some of both?
The length of your annotation will depend on the assignment or on the purpose of your annotated bibliography. After summarizing and assessing, you can now reflect on this source. How does it fit into your research? Is this a helpful resource? Too scholarly? Not scholarly enough? Too general/specific? Since "stem cell research" is a very broad topic, has this source helped you to narrow your topic?

Not all annotations have to be the same length. For example, this source is a very short scholarly article. It may only take a sentence or two to summarize. Even if you are using a book, you should only focus on the sections that relate to your topic.
Not all annotated bibliographies assess and reflect; some merely summarize. That may not be the most helpful for you, but, if this is an assignment, you should always ask your instructor for specific guidelines.

Using a variety of sources can help give you a broader picture of what is being said about your topic. You may want to investigate how scholarly sources are treating this topic differently than more popular sources. But again, if your assignment is to only use scholarly sources, then you will probably want to avoid magazines and popular web sites.
The bibliographic information above is proper MLA format (use whatever style is appropriate in your field) and the annotations are in paragraph form. Note also that the entries are alphabetized by the first word in the bibliographic entry. If you are writing an annotated bibliography with many sources, it may be helpful to divide the sources into categories. For example, if putting together an extensive annotated bibliography for stem cell research, it might be best to divide the sources into categories such as ethical concerns, scholarly analyses, and political ramifications.
For more examples, a quick search at a library or even on the Internet should produce several examples of annotated bibliographies in your area.
- Descriptive: This annotation describes the source without summarizing the actual argument, hypothesis, or message in the content. Like an abstract, it describes what the source addresses, what issues are being investigated, and any special features, such as appendices or bibliographies, that are used to supplement the main text. What it does not include is any evaluation or criticism of the content. This type of annotation seeks to answer the question: Does this source cover or address the topic I am researching?
- Informative/Summative: This type of annotation summarizes what the content, message, or argument of the source is. It generally contains the hypothesis, methodology, and conclusion or findings, but like the descriptive type, you are not offering your own 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?
- Evaluative/Critical/Analytical: This annotation includes your evaluative statements about the content of a source. It is the most common type of annotation your professor will ask you to write. Your critique may focus on describing a study's strengths and weaknesses or it may describe the applicability of the conclusions to the research problem you are studying. This type of annotation seeks to answer these types of questions: Is the reasoning sound? Is the methodology sound? Does this source address all the relevant issues? How does this source compare to other sources on this topic?

II. Choosing Sources for Your Bibliography
There are two good strategies you should use to begin identifying possible sources for your bibliography--one that looks back into the literature and one that looks forward.
- The first strategy is to identify several recent scholarly books or journal articles on the topic of your annotated bibliography and review the sources cited by the author(s). Often, the items cited by an author will effectively lead you to related sources about the topic.
- The second strategy is to identify one or more important books, book chapters, journal articles, or other documents on your topic and paste the title of the item in Google Scholar [e.g., from Negotiation Journal, entering the article, "Civic Fusion: Moving from Certainty through Not Knowing to Curiosity"], placing quotation marks around the title so Google Scholar searches as a phrase rather than a combination of individual words. Below the citation may be a "Cited by" reference followed by a linked number. This link will direct you to a list of other study's that have cited that particular item after it was published.
Your method for selecting which sources to annotate depends on the purpose of the assignment and the research problem you are investigating. For example, if the research problem is to compare the social factors that led to protests in Egypt with the social factors that led to protests against the government of the Phillippines in the 1980's, you will have to consider including non-U.S., historical, and, if possible, foreign language sources in your bibliography.
NOTE: Appropriate sources to include can be anything that has value in understanding the research problem. Be creative in thinking about possible sources, including non-textual items, such as, films, maps, photographs, and audio recordings, or archival documents and primary source materials, such as, diaries, government documents, collections of personal correspondence, meeting minutes, and official memorandums. Consult with a librarian if you're not sure how to locate these types of materials for your bibliography.
III. Strategies to Define the Scope of your Bibliography
It is important that the sources cited and described in your bibliography are well-defined and sufficiently narrow in coverage to ensure that you're not overwhelmed by the number of potential items to consider including. Many of the general strategies used to narrow a topic for a research paper are the same that you can use to define the scope of your bibliography. These are:
- Aspect -- choose one lens through which to view the research problem, or look at just one facet of your topic [e.g., rather than a bibliography of sources about the role of food in religious rituals, create a bibliography on the role of food in Hindu ceremonies].
- Time -- the shorter the time period to be covered, the more narrow the focus [e.g., rather than political scandals of the 20th century, cite literature on political scandals during the 1930s and the 1990s].
- Geography -- the smaller the region of analysis, the fewer items there are to consider including in your bibliography [e.g., rather than cite sources about trade relations in West Africa, include only sources that examine trade relations between Niger and Cameroon].
- Type -- focus your bibliography on a specific type or class of people, places, or things [e.g., rather than health care provision in Japan, cite research on health care provided to elderly men in Japan].
- Source -- your bibliography includes specific types of materials [e.g., only books, only scholarly journal articles, only films, etc.]. However, be sure to describe why only one type of source is appropriate.
- Combination -- use two or more of the above strategies to focus your bibliography very narrowly or to broaden coverage of a very specific research problem [e.g., cite literature only about political scandals during the 1930s and the 1990s and that have only taken place in Great Britain].
IV. Assessing the Relevance and Value of Sources
All the items you include in your bibliography should reflect the source's contribution to understanding the research problem or the overall issue being addressed. In order to determine how you will use the source or define its contribution, you will need to assess the quality of the central argument within the source. Specific elements to assess include an item’s overall value in relation to other sources on the topic, its limitations, its effectiveness in defining the research problem, the methodology used, the quality of the evidence, and the author’s conclusions and/or recommendations.
With this in mind, determining whether a source should be included in your bibliography depends on how you think about and answer the following questions related to its content:
- Are you interested in the way the author frames the research questions or in the way the author goes about answering it [the method]?
- Does the research findings make new connections or promote new ways of understanding a problem?
- Are you interested in the way the author uses a theoretical framework or a key concept?
- Does the source refer to and analyze a particular body of evidence that you want to cite?
- How are the author's conclusions relevant to your overall investigation of the topic?
V. Format and Content
The format of an annotated bibliography can differ depending on its purpose and the nature of the assignment. Contents may be listed alphabetically by author or arranged chronologically by publication date. If the bibliography includes a lot of sources, items may also be subdivided thematically or by type. If you are unsure, ask your professor for specific guidelines in terms of length, focus, and the type of annotation you are to write.
Your bibliography should include a brief introductory paragraph that explains the method used to identify possible sources [including what sources, such as databases, you searched], the rationale for selecting the sources, and a statement, if appropriate, regarding what sources were deliberately excluded and the reasons why.
This first part of your entry contains the bibliographic information written in a standard documentation style, such as, MLA, Chicago, or APA. Ask your professor what style is most appropriate and be consistent!
The second part should summarize, in paragraph form, the content of the source. What you say about the source is dictated by the type of annotation you are asked to write. In most cases, however, your annotation should provide critical commentary that examines the source and its relationship to the topic. Things to think critically about when writing the annotation include: Does the source offer a good introduction on the issue? Does the source effectively address the issue? Would novices find the work accessible or is it intended for an audience already familiar with the topic? What limitations does the source have [reading level, timeliness, reliability, etc.]? Are any special features, such as, appendices or non-textual elements effectively presented? What is your overall reaction to the source? If it's a website or online resource, is it up-to-date, well-organized, and easy to read, use, and navigate?
Annotations can vary significantly in length, from a couple of sentences to a couple of pages. However, they are normally about 300 words. The length will depend on the purpose. If you're just writing summaries of your sources, the annotations may not be very long. However, if you are writing an extensive analysis of each source, you'll need to devote more space.
