This section is divided by type of document: books, articles, and websites. You will learn to apply the CRAP criteria to each of them.
Currency: When was the information published? Has it been revised or updated?
Reliability: Is the information accurate? Where does it come from?
Authority: Who is the author and is the author qualified to write on the topic?
Purpose: Why was this information published? Is it fact, opinion or propaganda?
