Evaluate Sources

Evaluating information encourages you to think critically about the reliability, validity, accuracy, authority, appropriateness, opinion or bias of information sources. The task of the annotated bibliography is to find the most relevant, accurate, authoritative and, when appropriate, current sources that meet your research needs.              


One evaluation method to use is the "CRAAP" Test criteria (see Infographic below). This test was originally developed by the Meriam Library at California State University, Chico in 2010. The test is a set of evaluation criteria that can be applied to websites, articles and other information sources to help you determine if the information is reliable. If the information doesn't pass the test, you probably should not use it in your assignment.


You may have found more sources than you need for the Annotated Bibliography. Use the CRAAP test to rank the sources you have found. For example, a book by a leading authority could get more points than a book by a first-time author.
