The "Hidden Web"

(AKA "Deep Web" AKA "Invisible Web")

Hidden Web Definition

The Hidden Web is defined as:
Content on the Web that is not found in most search engine results, because it is stored in a database rather than on HTML pages. Viewing such content is accomplished by going to the Web site's search page and typing in specific queries. LexiBot was the first search engine to actually make individual queries to each searchable database that it finds (see LexiBot). Also known as the "invisible Web." Contrast with surface Web. See also deep link.

(2) Password-protected content on the Web available only to members and subscribers.
