Definitions

A bibliography is a list of sources (books, journals, Web sites, periodicals, etc.) one has used for researching a topic. Bibliographies are sometimes called "References" or "Works Cited" depending on the style format you are using. A bibliography usually just includes the bibliographic information (i.e., the author, title, publisher, etc.).

An annotation is a summary and/or evaluation. Therefore, an annotated bibliography includes a summary and/or evaluation of each of the sources. Depending on your project or the assignment, your annotations may do one or more of the following.

  • Summarize: Some annotations merely summarize the source. 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? The length of your annotations will determine how detailed your summary is.

    For more help, see our handout on paraphrasing sources.

  • Assess: After summarizing a source, it may be helpful to evaluate it. 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?

    For more help, see our handouts on evaluating resources.

  • Reflect: Once you've summarized and assessed a source, you need to ask how it fits into your research. 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?

Your annotated bibliography may include some of these, all of these, or even others. If you're doing this for a class, you should get specific guidelines from your instructor.

Why should I write an annotated bibliography?

To learn about your topic: Writing an annotated bibliography is excellent preparation for a research project. Just collecting sources for a bibliography is useful, but when you have to write annotations for each source, you're forced to read each source more carefully. You begin to read more critically instead of just collecting information. At the professional level, annotated bibliographies allow you to see what has been done in the literature and where your own research or scholarship can fit. To help you formulate a thesis: Every good research paper is an argument. The purpose of research is to state and support a thesis. So, a very important part of research is developing a thesis that is debatable, interesting, and current. Writing an annotated bibliography can help you gain a good perspective on what is being said about your topic. By reading and responding to a variety of sources on a topic, you'll start to see what the issues are, what people are arguing about, and you'll then be able to develop your own point of view.

To help other researchers: Extensive and scholarly annotated bibliographies are sometimes published. They provide a comprehensive overview of everything important that has been and is being said about that topic. You may not ever get your annotated bibliography published, but as a researcher, you might want to look for one that has been published about your topic.

Format

The format of an annotated bibliography can vary, so if you're doing one for a class, it's important to ask for specific guidelines.

The bibliographic information: Generally, though, the bibliographic information of the source (the title, author, publisher, date, etc.) is written in either MLA or APA format. For more help with formatting, see our MLA handout. For APA, go here: APA handout.

The annotations: The annotations for each source are written in paragraph form. The lengths of the annotations can vary significantly from a couple of sentences to a couple of pages. 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 more space.

You can focus your annotations for your own needs. A few sentences of general summary followed by several sentences of how you can fit the work into your larger paper or project can serve you well when you go to draft.

Overview

A bibliography is a listing of the books, magazines, and Internet sources that you use in designing, carrying out, and understanding your science fair project. But, you develop a bibliography only after first preparing a background research plan — a road map of the research questions you need to answer. Before you compose your bibliography, you will need to develop your background research plan.

With your background research plan in hand, you will find sources of information that will help you with your science fair project. As you find this information it will be important for you to write down where the sources are from. You can use the Bibliography Worksheet to help you, just print out a few copies and take them with you to the library. As you find a source, write in all of the necessary information. This way, when you are typing your bibliography you won't need to go back to the library and find any missing information. The more information you write down about your source, the easier it will be for you to find if you want to read it again.

When you are writing your report, you will use the sources in your bibliography to remind you of different facts and background information you used for your science fair project. Each time you use some information from a source, you will need to cite the source that it came from. To cite a source, simply put the author's name and the date of the publication in parentheses (Author, date) in your text. If the person reading your report wants to find the information and read more about it, they can look up the reference in your bibliography for more detail about the source. That is why each source you use must be listed in a detailed bibliography with enough information for someone to go and find it by themselves.

Your bibliography should include a minimum of three written sources of information about your topic from books, encyclopedias, and periodicals. You may have additional information from the Web if appropriate.

Examples of Bibliography Formats

There are standards for documenting sources of information in research papers. Even though different journals may use a slightly different format for the bibliography, they all contain the same basic information. The most basic information that each reference should have is the author's name, the title, the date, and the source.

Different types of sources have different formatting in the bibliography. In American schools, the two most commonly used guidelines for this formatting are published by the MLA (Modern Language Association) and the APA (American Psychological Association).

The MLA guidelines call for the bibliography to be called Works Cited. Science Buddies has summarized some of the most common MLA formats for your use: MLA Format Examples.

The APA guidelines call for the bibliography to be called the Reference List. Science Buddies has summarized some of the most common APA formats for your use: APA Format Examples.

Your teacher will probably tell you which set of guidelines to use.

On the Science Buddies website we use the following guidelines:

  • APA format for online sources
  • MLA format for all other sources
  • APA (author, date, page) format for citations in our articles

Getting Started

Download and print the Science Buddies Bibliography Worksheet. Keep several copies with you and fill in the information as you do your research. When you are finished, type the information from the worksheet into a formatted bibliography using the examples listed above.
