Searching Google

If you're doing an Internet search for a research paper, you have to be careful about what Web sites you use. Usually, Web sites made by the government (.gov), universities (.edu), and some non-profit organizations (.org) have the best information.

Quick Google tip: After your keyword, add one of these-

site: gov

site: edu
site: org

You'll have fewer Web sites to look through, and they'll be more reliable than a lot of .com Web sites.
