Accessing information is a complex process. One must learn methods for rapid, accurate retrieval of information, as well as acquire the ability to differentiate between valid and invalid sources of retrieved information.

In general source evaluation, one examines a piece of information as it is acquired and makes an immediate determination as to the appropriateness of the information. If the information is not appropriate for the task at hand, it is discarded.

Refined source evaluation occurs after one has acquired several pieces of seemingly valid information. The different pieces of information are sorted and classified according to quality and relevance.
