A web is essentially a way of defining a context or database in which a typically large set of related block, link, keyword, and path information is stored. The web allows individual users, groups of users, or, in the extreme, an entire campus to create a shared web of materials from different applications. Two webs might exist that reference the same documents but have an entirely different set of links. (27)

For our purposes, a web is a user-specific set of links which may be saved and restored at will. This concept is similar to that of the tour, the main distinction being that a tour is one coherent path while the web presents many paths.

Note that this definition of "web" has nothing to do with the World Wide Web.
