Selected Search Engine Information:

![[Alta Vista]](images/alta6.gif)
- Alta Vista began as a way for Digital Corporation to show off some new technology -
their new line of Alpha servers. Alta Vista came online last December and has been
handling more than two million hits a day. If its claim to more than 30 million fully
indexed pages is accurate, it wins bragging rights as the largest of the Web-search
databases. FTP sites and Gopher sites are not included in searches, but Newsgroups are
included. You cannot refine search results, but it does offer case-sensitive searching. It
uses Boolean or similar operators in its advanced searching routines.
-
- BigBook, Inc. was founded in 1995 to build a whole new kind of Yellow Pages. A
Yellow Pages that would include all the business information that consumers need -
and features to let them get to the information quickly and easily. At the same time,
BigBook helps local businesses provide details about their products and services,
cost-free. BigBook makes it easier for consumers and businesses to hook up with each
other, and provides "value-added" information to help consumers make better, more
informed decisions.

![[Magellan]](images/magellan.gif)
- Magellan is the product of a marriage between McKinley's proprietary search
technology and its unique editorial process. Sites in the Magellan guide are reviewed
and rated by a highly informed editorial staff, with expertise in topical areas. The
resulting site evaluations not only provide users with in-depth information, but also a
human voice. Magellan recently introduced the concept of the "Green Light" indicator.
Sites in Magellan bearing the Green Light icon have been identified as being free of
adult-oriented content at the time of their review. In addition to the 40,000 reviewed
and rated sites, Magellan contains over 15 million URLs.
-
![[Excite!]](images/excite.gif)
- Architext Software's fast, full-text search covers more than 1.5 million indexed Web
pages, or 50,000 reviewed sites. Or try a concept search. Concept searches will find a
page related to the words you search on, even it those words are not actually on the
Web page. It's like searching an index combined with a thesaurus. (BTW, what's
another word for thesaurus? - Steven Wright) FTP sites and Gopher sites are not
included in searches, but Newsgroups are included. You cannot refine search results,
and it does not offer case-sensitive searching.
-
![[Galaxy]](images/galaxy.gif)
- Galaxy was begun in the summer of '93, and went online January '94. It's the oldest
browsable/searchable web directory, and has always included a Gopher and Telnet
directory in addition to the web information. Searching represents about one-half of the
Web traffic at Galaxy. The index includes only those pages actually submitted to
Galaxy. Periodically, Galaxy re-indexes sites linked to them. During this process, they
discover (and fix, where possible) bad links. They also search for the "we have moved"
sort of pages, and repair those entries.
-
![[WebCrawler]](images/webcrawl.gif)
- WebCrawler was the first full-text search engine on the Internet. Several competitors
emerged within a year of WebCrawler's debut: Lycos, InfoSeek, and
OpenText. They all improved on WebCrawler's basic functionality, though they did
nothing revolutionary. WebCrawler's early success made their entry into the market
easier, and legitimized businesses that today constitute a small industry in Web
resource discovery.
-
![[Yahoo]](images/yahoo.gif)
- Yahoo! contains organized information on tens of thousands of computers linked to the
Web. The San Jose Mercury news recently noted that "Yahoo is closest in spirit to the
work of Linnaeus, the 18th century botanist whose classification system organized the
natural world."
