Abstract:

This tutorial presents a brief overview of the reasons to evaluate information you find on the Internet, offers guidelines to assist you in the process, and helps you assess the information found on sample Web pages. Although the principles presented here apply to all kinds of information found on the Internet, the primary focus is on sites from organizations and companies-sites that you will likely visit while conducting research-rather than on personal Web sites.
