This document provides guidance on evaluating information sources. It introduces several models for evaluating sources, including the CRAAP test and the relevance/credibility model. The CRAAP test examines the currency, relevance, authority, accuracy, and purpose of a source. Additional factors discussed for evaluating sources include the author's qualifications, whether the information has been peer reviewed, potential biases, and accuracy. Students are encouraged to consider these criteria when evaluating both online and print sources for a research task or assignment. The document stresses the importance of carefully evaluating all sources, especially web-based materials, given the open nature of online information.
