Why Evaluate?

Locating information, whether in traditional print format or in electronic format, is only the first step in doing research. The next step is to evaluate the quality and the usefulness of what you find.

When using websites, the evaluation process is more important than ever since anyone who has an account on a computer linked to the Internet can put up a website. They don't have to be intelligent or knowledgeable, scholarly or authoritative, and in most cases, the "information" they put on these pages does not have to pass any kind of scrutiny or editing process.

Many institutional and organizational websites include statements about the types and sources of information that is provided on their sites, as well as the purpose of the organization itself. If this information is not offered, be especially careful about evaluating the data you find there.

When evaluating printed texts or electronic documents, consider the following criteria:

Currency  ||  Relevance  ||  Authority  ||  Accuracy  ||  Objectivity

The CRAAP Test
