Resources - Deep Web Sources

I was first introduced to the terms ‘deep web’ and ‘surface web’ by Professor James Backer at the Cambridge College inthe summer program of 2005. The terms were associated with the imagery of fishing where searching on the Internet is contrasted to fishing in the deep or just surface fishing. These sessions certainly enabled me to have a different perspective of the varying aspects of the web and search engines. Michael K. Bergman writing in the Journal Of Electronic Publishing indicated that searching on the Internet can be compared to dragging a net across the surface of the ocean. He contends that most of the web’s information in missed when using traditional search engines. This information is available for viewing at the attached link.

Difference between deep web and surface web

Paul Pedley writing on “The Invisible Web: Searching the inner part of the Internet” uses the terms ‘visible web’ and ‘invisible web’. His views adapted from his writing (page 4) are as follows

The visible web is the “publicly indexable” or “surface web”—those websites that have been picked up and indexed by the search engines.

The phrase “the invisible web” refers to information that search engines can’t or don’t index. The content that resides in searchable databases, for example, cannot be indexed or queried by traditional search engines because the results are generated dynamically in response to a direct query.

Administrators must be willing and encouraged to investigate resources wherever they are. This page should shed some light on this ‘fishing’ expedition whether the fish are visible or invisible.
