INVISIBLE or DEEP WEB

The Invisible Web Finding Hidden Internet Resources Search Engines Can’t See: “A directory of some of the best resources the Invisible Web has to offer. The directory includes resources that are informative, of high quality, and contain worthy information from reliable information providers that are not visible to general-purpose search engines.”

direct search “is a growing compilation of links to the search interfaces of resources that contain data not easily or entirely searchable/accessible from general search tools like Alta Vista, Google, or Hotbot. Although these “general” tools are essential for the retrieval of Internet based data, searchers often fail to realize that a massive amount of information is not easily or entirely searchable/accessible via these search tools.  Material “hidden” from the general search tools is said to reside on the Invisible Web.”

INFOMINE “is a virtual library of Internet resources relevant to faculty, students, and research staff at the university level. It contains useful Internet resources such as databases, electronic journals, electronic books, bulletin boards, mailing lists, online library card catalogs, articles, directories of researchers, and many other types of information.”

CompletePlanet “There are hundreds of thousands of databases that contain Deep Web content. CompletePlanet is the front door to these Deep Web databases on the Web and to the thousands of regular search engines — it is the first step in trying to find highly topical information. By tracing through CompletePlanet’s subject structure or searching Deep Web sites, you can go to various topic areas, such as energy or agriculture or food or medicine, and find rich content sites not accessible using conventional search engines.

BrightPlanet initially developed the CompletePlanet compilation to identify and tap into many hundreds and thousands of search sources simultaneously to automatically deliver high-quality content to its corporate and enterprise customers. It then decided to make CompletePlanet available as a public service to the Internet search public.”
