Why should I use Web sites?
How do I find good Web sites?
Start by reviewing the Web Searching Guide for expert advice on the best search engines--both general and specialized.
Of particular note are the "academic web resources" which includes a link to Google Scholar and other search engines that focus on, credible, scholarly information available on the Web.
note: no single search engine comes close to indexing all of the Web. Be sure to search two or three different search engines if you want to be thorough.
For every major, most minors, and other special topics, librarians have put together a subject guide with links to quality sites (near the bottom of the guide).
For quick and mainly free Web-based reference information such as encyclopedias, check out the on-line reference page.
