Imagine a world in which every single person on the planet is given free access to the sum of all human knowledge. That's what we're doing.

Wikipedia was founded in 2001 as a project to build an online, free-access, free-content encyclopedia entirely from scratch. Since then, it has grown to be the largest encyclopedia ever created, comprising more than five million articles in English, while still relying on the contributions of volunteers. The English Wikipedia community thanks the millions of users whose edits over the past fourteen-plus years have made this remarkable accomplishment possible.

A brief history

Wikipedia officially launched on 15 January 2001, with Jimmy Wales and Larry Sanger as its leaders, on a single computer server as the successor to Nupedia. Its first major mainstream media coverage was in The New York Times on 20 September 2001. In the first year of its existence, more than 20,000 encyclopedia entries were created – a rate exceeding 1,500 articles per month. Today, there are Wikipedia editions in more than 200 languages, accompanied by a dozen additional free-content projects, such as Wikimedia Commons. In March 2006, the English Wikipedia reached one million articles. According to Alexa, Wikipedia is currently the world's sixth most popular website, receiving approximately eight billion pageviews per month. We reached five million articles on 1 November 2015.

A work in progress

While Wikipedia is an incredible success, it remains a work in progress. There are still great gaps in its coverage with millions of important topics missing from its pages. Many articles – even vital ones – are not yet considered high-quality. Of our five million articles, only a few tens of thousands have passed a vetting process for good or featured status, and more than half are short stubs or start-class articles. There are also more than 200 non-English-language editions of Wikipedia that need volunteers. In other words, there is still much work to be done – and you can help!

How you can help

Wikipedia is written by the people who use it. Anyone, regardless of background, can contribute to building the encyclopedia. You don't even have to register an account (though there are good reasons to do so). If you find an article you can improve, edit the article to make it more accurate and useful for others. Each page contains edit buttons for you to make those changes immediately. Any improvement, whether it's fixing a typo or drafting a brand new article, is greatly appreciated.

Wikipedia values boldness and the pursuit of consensus. Don't be afraid or disillusioned if your first contributions are undone – Wikipedia is a collaborative project, which means that sometimes we disagree. That's okay. Each page on Wikipedia has a talk page dedicated to discussing improvements, and fellow editors have a talk page where you can contact them individually.
