The deep Web contains nearly 550 billion individual documents compared to the one billion of the surface Web. The deep Web is the largest growing category of new information on the Internet. Deep Web sites tend to be narrower, with deeper content, than conventional surface sites. A full ninety-five per cent of the deep Web is publicly accessible information not subject to fees or subscriptions.
