Document Summary

So far we have considered the web as a medium in which publishers organize materials for consumers to read. Wikis were introduced to the web in 1995 as an application in which every user could be an author and editor, as well as a reader, of content. The most significant wiki to date is wikipedia, which began in 2001 as an open encyclopedia and today has several million articles[1] on topics covering historical events, scientific achievements, global and local geographic information, and a host of trivia. Wikis provide users with a shared electronic notebook that can grow as large as needed. Contributors can easily start a new page in the notebook, or add information to a page that"s already there. Importantly, they can also go back to see previous versions of any page, see who made each change (and why), and easily restore any page to any of its previous versions.
