Annotated Bibliography Examples in APA and MLA Style

Bibliographies are used to cite sources that are used in a research paper. An annotated bibliography is more than a mere list of sources. It includes:

  • A summary - includes information that explains what information the source provides
  • An evaluation - explains why or how the notation is a useful source. It can also speak to the validity of the source in terms of its scholarly nature
  • An explanation of value - speaks to the relevance of the citation to the research paper

Some annotated bibliographies offer only summaries, while others offer all three components. It is important to assess what the audience of the research paper will be seeking before crafting an annotated bibliography.

Annotated Bibliography Format Styles

The basic format of an annotated bibliography is the same as a non-annotated bibliography entry. The difference is that the publication information about the source material is followed with the annotation that reviews and evaluates the material.

APA (American Psychological Association) Style

Baker, T. (1995). Gun control and you. Stevenson Learning Law Review, 45 (2), 180-193.

The author researches several federal and state firearms regulations and their effect on the everyday citizen. By testing his hypothesis that firearms regulations have an inherent effect on everyday citizens, findings yield in support of the hypothesis.

MLA (Modern Language Association) Style

Johnson, Jaime. "Gun Control: Your Only Means of Defense.” Researcher's Special Journal (1999): 254-325.

The author researches several federal and state firearms regulations and their effect on the everyday citizen. By testing his hypothesis that firearms regulations have an inherent effect on everyday citizens, findings yield in support of the hypothesis. In contrast, Baker cited in an earlier study the complete opposite.

Creating an Annotated Bibliography

Some final tips for creating a well-annotated bibliography are:

  • Consider which writing style is required for your research. There are differences between APA and MLA format. Your instructor or publisher will provide guidelines.
  • Use the third person when writing.
  • Make a list of the points which the author emphasized as relative to the topic that you were researching.
  • Make sure that the sources you used are aligned or in agreement with your stance on the research issue. This helps to make a stronger argument for your stance on the issue that you researched.

Your annotation should be succinct, so summarize the content, providing only information that describes and evaluates the source material.
