Evaluate Your Sources

Evaluation is essential

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 and TRAAP are two examples.

How do you know which sources of information to trust? Use one or both of these methods.
