Google
The most extensive search engine on the Web. Google search results are ranked based on site popularity rather than the common practice of paid positioning. Google also has specialized searches for certain operating systems, government documents, maps and scholarly articles. A single click translation service is available for most pages which will translate to the user's primary language. It also caches Web pages allowing an individual to view pages that are not currently available or that are on overburdened servers.

HotBot

Yahoo
Yahoo is a collection of classified subject resources. If no matches are found in its own database, it searches the rest of the Web using Google. Options at the bottom of the screen link to searches in a particular country (Denmark, France, Mexico) or city (Los Angeles, New York City) which may be in the native language of that country.

Meta Search Engines
These search engines search multiple databases simultaneously. Both of these search engines remove the duplicates before presenting the search results.
Dogpile
Searches the major search engines simultaneously and allows the user to view the combined results or compare the results of the various engines side by side.

MetaCrawler

Subject Guides
These subject guides are a starting point to specific information on the Web. Although they do provide search engines, those engines search only on the individual Web site (i.e., a search on the Librarians' Index to the Internet will only show sites listed on the Librarians' Index to the Internet).
Internet Public Library
Originally begun as a project of the University of Michigan School of Information and Library Studies, the Internet Public Library locates, evaluates, annotates and organizes the information resources of the Internet which would be of interest to patrons of a public library.

Librarians' Index to the Internet
The Librarians' Index to the Internet is a searchable, annotated subject directory of more than 5,800 Internet resources selected and evaluated by librarians for their usefulness to users of public libraries. It is now produced by the Berkeley Digital Library SunSITE at the University of California at Berkeley.
