There are currently more than 7,000 specialized databases on the web. Each creates dynamic web pages on demand based on user input. Hundreds of other web sites use databases to create their web content on the fly. Two resources, Beaucoup and Lycos , help users manage this dilemma. Beaucoup's sole purpose is to provide an index of searchable databases.
Users can search for a database containing the appropriate information they seek.
Often these databases contain information that cannot be found elsewhere on the web. Users can browse listings, or Lycos will suggest appropriate databases within its own search results. If you click through, you'll discover some important cancer-related sites listed, with links that lead straight to their search pages. You can then select a resource and try a specific search there. So to get the most out of the Invisible Web Catalog, change your search strategy at Lycos.
