Annotate Your Bibliography

The purpose of an annotated bibliography is to describe the cited material, whether a book, article or other type of source. It is a brief, descriptive note that should provide sufficient information so that a determination can be made as to whether the source should be examined further for use. Annotations help to to clarify each source, and they will often provide evaluative information as well.

Annotations are NOT book reviews. Be careful as you begin that you do not create a book review. An annotation also differs from an abstract, as an abstract is simply a summary of the content. The annotation provides information for determining the usefulness of an individual work.

Writing Reliability Statements

Consider the following points when you are writing your reliability statement:

  • Who is the publisher? Is the source scholarly?
  • What are the author's credentials?
  • When was it published? Do you need current information?
  • Where and how did you find this? If you found it through the library, what is the name of the database?
  • If it is a web source, what is the domain?
