Not all search engines are alike. Some are just better and
faster at finding the precise information that you want. Some
of our favorite search engines are:
Google (http://www.google.com/)
is the best general search engine. It finds PDF files, images,
maps and addresses, and can search within specific sites.
Yahoo (http://www.yahoo.com/) classifies the Web by subject, just like
a library catalog. Its search engine finds category and site matches from its subject catalog of the Web, and Web
page matches from the Google search engine.
