A Wiki library is a document library in which users can easily edit any page. The library grows organically by linking existing pages together or by creating links to new pages. If a user finds a link to an uncreated page, he or she can follow the link and create the page.
In business environments, a Wiki library provides a low-maintenance way to record knowledge. Information usually traded in e-mail messages, gleaned from hallway conversations, or written on paper can instead be recorded in a Wiki library, in context with similar knowledge.
Other example uses of Wiki libraries include brainstorming ideas, collaborating on designs, creating an instruction guide, gathering data from the field, tracking call center knowledge, and building an encyclopedia of knowledge.
