Deep Web Research 2012

Marcus Zillman's annual deep/invisible web research report is now available on LLRX. The report includes an impressive number of articles on the deep web, and an extensive list of search engines (including verticals) and tools for locating this content, which never get indexed by any of the big search engines.

"The Deep Web covers somewhere in the vicinity of 1 trillion plus pages of information located through the world wide web in various files and formats that the current search engines on the Internet either cannot find or have difficulty accessing. The current search engines find hundreds of billions of pages at the present time of this writing."

This is the 8th annual deep web research report.
