Wikipedia is a peer-directed project to create a group of online encyclopedias in every major language. Founded in 2001, Wikipedia grew exponentially in its first 4 to 5 years. It is the world's largest encyclopedia project and one of the most popular sites on the Internet.[1] The English-language Wikipedia is the world's largest single wiki and contains nearly two million articles.
Main features
Wikipedia refers to two of its pivotal features in its slogan, "the free encyclopedia that anyone can edit." Indeed, virtually any person on the Internet may create or edit a Wikipedia article, thanks to computer software known as a wiki. Contributors may edit Wikipedia anonymously or register permanent "user" accounts. Currently, Wikipedia has more than ten thousand users.[2]
Wikipedia keeps fastidious track of its participants' editing and much of its internal activities using the wiki software. All edits are tracked and the editing history for every Wikipedia page is available.[3] As a result, when anonymous (or registered) users make inappropriate revisions to an encyclopedia article (i.e., Wikipedia "vandalism"), Wikipedia volunteers can readily restore the prior version.This transparency also enables visitors to examine both the history of substantive articles and the deliberations of Wikipedia's policy and organizational decisions, which are often effectuated through wiki webpages.
Wikipedia judges certain articles to be important enough and well-written enough to be considered featured articles, as of 9 May 2007, there are 1391 "Featured Articles" out of 1,776,624 articles on the English Wikipedia.[4] In addition, various groups of users collaborate within topical "projects" to rate the quality of articles and upgrade weaker articles.
Wikipedia may be said to be free insofar as its articles provide free and open access to all content, thereby creating public domain products. All contributions of text are licensed under the Gnu Free Documentation License (GFDL).
While anyone may contribute anonymously, anonymous contributors may be partially identified by the IP address from which they contributed.
Wikipedia articles include both knowledge typical of printed encyclopedias as well as relatively recondite subjects, such as information on small towns, minor sports figures and celebrities, and popular culture. For example, each of the 493 Pokemon characters has an individual article.
History
The project was started by Jimmy Wales and Larry Sanger in January 2001 as an accidental spin-off of Nupedia, a defunct online encyclopedia written by experts. Wales, however, no longer considers Sanger a co-founder of Wikipedia.
The project wrote its own wiki software called MediaWiki and released this software under the GPL, permitting anyone to copy it and to modify it freely. In addition, Wikipedia has established a series of related projects, such as a dictionary (Wiktionary), a news service (WikiNews), and a copyright-free repository of historical and literary texts (WikiSource).
Criticisms and controversies
Due to Wikipedia's practice of allowing anonymous editing by anyone at all, it has been criticized for factual inaccuracy and for vulnerability to vandalism. A notorious incident involving Wikipedia's inaccuracies was the John Seigenthaler biography controversy, in which an anonymous Wikipedia editor wrote a biography of a John Seigenthaler alleging that Seigenthaler was involved in the assassination of Robert F. Kennedy. [5]
Forks and spin-offs
The concept of Wiki's collaborative projects, along with criticisms of Wikipedia, has led to the emergence of several forks and spin-offs of Wikipedia. Examples include Wikinfo, a fork created by Fred Bauder; Conservapedia, a Wiki-style encyclopedia for political conservatives; and New World Encyclopedia, an encyclopedia written by experts that will launch in 2008.[6] Citizendium, an encyclopedic project established by Larry Sanger, the co-founder of Wikipedia, was originally a Wikipedia fork. Citizendium differs primarily from Wikipedia in that it only allows users with real-name registration to edit, while giving experts in a particular field more authority regarding its content.
Notes

- ↑ [1]. A small number of users are blocked or temporarily banned from using the Wikipedia site, mainly due to repeated tampering with the site.
