•A Web
directory is a listing of hyperlinks to
Web pages that is organized
into hierarchical categories.
•The difference between a search engine and a Web
directory is that people select the Web pages to include in a Web
directory.
•Many directories allow a Web page to be indexed in
several different
categories.
•The main weakness of a directory is that you must know
which category is likely to
yield the information you desire.
•Yahoo! is one of the
oldest and most respected directories on the Web.
