The goal of Wikipedia, the largest encyclopedia in history, is to create free encyclopedias in all languages of the world. Anyone with Internet access is free to contribute by writing new articles and editing existing articles. Wikipedia was ranked the fourth most visited website on the internet in November 2008 according to comScore.
Wikipedia started in January 2001, and currently offers over eleven million articles in over 260 languages. The largest Wikipedia is in English, with more than 2.6 million articles; followed by the German and French editions, each of which contain more than six hundred thousand articles. Nine other language editions contain 200,000+ articles, and more than 150 other languages contain 1,000+ articles. Wikipedia is entirely created and maintained by a community of active volunteers.
