This document introduces the CARR method for evaluating sources of information. CARR stands for Currency, Authority, Reliability, and Relevance. It explains that when evaluating a source, one should consider how old the information is and whether it has been updated, who authored the information and their qualifications, whether the information can be proven or verified, and whether the information is relevant to the topic being researched. The document provides questions to consider under each element of CARR to help determine the trustworthiness and usefulness of a source.
