Evaluate Your Sources: Summary

Evaluating the information you find, whether in print or digital format, is an essential aspect of doing research. The criteria for evaluation (accuracy, authority, bias/purpose, currency, and relevance) are interconnected. Take everything into account to determine how well the information source addresses your specific information needs. Librarians create mnemonic devices to help students learn and apply evaluation criteria to information. ACRAB, CAARP, and TRAAP are examples.

How do you know which sources of information to trust? Use one of these three methods. Be aware that your teacher may require you to use one over the other.






Avoid falling into an information trap. Learn to think critically about the source of information and the information within each source by applying the T.R.A.A.P. evaluation criteria. Once acquired, the habit of critical analysis will serve you in everything you read.
