One hypertext document can contain links to many other documents, and words or graphics may act as links to other documents. There are several different ways to begin a search on the Web to find specific information. There are two basic ways to begin a search. First, you could look at a subject directory. A subject directory is a database of Internet files submitted by site creators or evaluators and organized into subject categories.
Subject directories vary so it is best to try several different subject directories.
Second, you could use a search engine. A search engine is software that allows you to search for relevant Web sites after entering a term or phrase. Search engines can be a part of a subject directory or exist alone. The distinction between subject trees and search engines are becoming blurred as the functions of both are being represented at some sites. The University Library System's Digital Library has a site that lists useful subject directories and search engines.
