The "Deep Web." The Hidden Web." The "Invisible Web." All of these terms refer to the same thing: websites that cannot be accessed by search engines such as Google or Yahoo. Reuters estimates that there are 550 billion websites in total, while Google only accesses about 1.4 billion. It takes specialized knowledge to access-and navigate-the Hidden Web.

"This is a valuable tome for a web beginner or one who wishes to share some of the information it contains with others. . . . Recommended." - Teacher Librarian "Each site appears in boldface type followed by the URL, with a description taken from the site itself in many instances. The conclusion reiterates the need for proficient search skills in order to find these hidden resources and that, in spite of what many students believe, Google is not the only way to find information. A bibliography and extensive index conclude this straightforward, accessible guide to exemplary research." - School Library Journal "Many of the Websites included in this publication are great resources containing valuable information that is fully or partially unavailable through search engines. . . . The Hidden Web does succeed in providing a number of educational and worthwhile research sources that many users are ignoring by relying solely on search engines." - ARBA "Keep this readily accessible on your office bookshelf." - School Librarian's Workshop
