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.

Use Google and other sources to research the authors, organizations, or institutions responsible for the page and for its funding.
Don't just trust the "About" page!
Currency - when was the page written or updated? Is the info current enough for your topic?
Authority - who wrote the page? Is there eveidence that the author or oraganization is an expert on this subject?
Reliability - Are there references given for the info on the site? Is the info supported by evidence? Can this info be verified?
Purpose - is this info fact, opinion, propaganda? Is there a bias? Is the purpose to inform, sell, entertain, persuade?
