Module 5: Untangling The Web>> Untangling the Web
Millions of Web pages are available to you, but how do you find the best ones for your research?
Remember that many libraries, including those at Stanford, review and organize Web pages. Starting with the libraries' home page will help you quickly locate quality sites. To find other information on the Web you will need to use a search engine.
Each search engine uses software (called spiders or robots) to compile a database of pages found on the publicly accessible Web. When you enter a search, the search engine scans its own database to match your terms against terms in the pages of its database.
So, each search engine searches the part of the Web it has collectednot the whole Weband each search engine has a somewhat different database.
