.com - Commercial. The intent of the site is to sell goods or services, as well as provide information about the company.
.org - Organization, usually non-profit. The intent of the site is to present information collected by or about the organization. Sometimes, the intent of the site is to promote a particular point of view.
.net - Network, usually personal Web pages. The intent of the site is as varied as the individual(s) responsible for the content.

Searching the Internet
Advanced Google Searching
Google offers many search techniques to help refine results, similar to what can be done in a library database. For example:
- Enclose keywords in quotes to search an exact phrase: "san fernando valley"
- Enclose in parentheses and separate with OR to retrieve any of those keywords in the results: (csun OR "california state university northridge")
- Add a minus sign to remove webpages containing a keyword or phrase: -parking
- Limit search to specific website: site:.calstate.edu
- Limit search to specific domain: site:.gov
- Limit results by date of last update: From the results screen, click Search Tools and select time period from the Anytime menu
- Get definitions or explanations of terms: define keyword/phrase, i.e., define "fiscal cliff"
- Watch the Advanced Google Searching video for more help.
