Evaluating Sources using the CRAAP Method

After you retrieve a list of resources, it is important to evaluate any source you are interested in using to determine the quality of the information provided in the source. Common evaluation criteria include currency, relevance, authority, accuracy, and purpose. The use of these criteria in evaluating research resource is sometimes called the CRAAP method. See the chart below for a more in-depth explanation of what to look for in each resource.
