Library Research Process

This guide provides introductory information and tips on the research process.

Evaluating Sources

Not all information is created equal. This is especially true of information found on the open web, via Google or other search engines. There is wonderful, high-quality information to be found there. And there is utter crap. And everything else in-between. Whether for one of your courses or for your personal use, one of the key parts of the research process is evaluating your information, i.e., using your Crap Detector.

In this video, librarian Sherri Saines talks about evaluating information sources.
