Search Engines - Bruce, Chien, and Jered

* definition
- A Web search engine is a tool designed to search for information on
the World Wide Web. Information may consist of web pages, images,
information and other types of files. Some search engines also mine
data available in newsbooks, databases, or open directories. Unlike
Web directories, which are maintained by human editors, search engines
operate algorithmically or are a mixture of algorithmic and human
input.

Yahoo!, Magellan, Lycos, Infoseek and Excite.

Yahoo! - late 1990s, US, started as a web directory of other websites,
