Introduction to Wikipedia, the Free Online Encyclopedia
Wikipedia is a multilingual free online encyclopedia created and maintained as an open collaboration project by a community of volunteer editors. It is the largest and most popular general reference work on the internet, featuring over 6 million articles in over 300 languages on a huge range of topics. Wikipedia was launched in January 2001 by Jimmy Wales and Larry Sanger and is currently hosted by the non-profit Wikimedia Foundation.
History and Development
The concept of a free, open content encyclopedia that could be written collaboratively by anonymous volunteers was first proposed by Larry Sanger in 2000. The first Wikipedia article was “Hello world”, which was created on January 15, 2001 and was edited just a few hours later to become “Hello Wikipedia” which became the first official article. Throughout 2001 the site experienced steady growth as more editors joined to write and expand articles on various topics. By the end of 2001 there were around 20,000 articles online in English.
In January 2002, the site launched its second language version in German and continued expanding internationally. In 2003 Wikipedia achieved over 100,000 articles and in July it launched its version 1.0 project to improve the stability and usability of the site interface through additional funding from the non-profit Wikimedia Foundation. In 2004 Wikipedia achieved over a million articles and continued steady growth through efforts to attract more global content and languages. As of 2023, there are over 6.2 million articles in the English Wikipedia alone and over 6.8 million total across all language editions combined.
Content and Features
Wikipedia features a vast scope of human knowledge, with over 6 million articles on countless topics in over 300 different languages. Articles range from comprehensive histories of countries, biographies of famous people, explanations of scientific and medical topics, to more niche articles on pop culture, hobbies, and obscure historical events. As an open collaboration project, anyone can contribute to Wikipedia by creating new articles or editing existing ones, provided they follow basic content policies regarding topics being factual, verifiable from reliable sources, and presenting multiple points of view fairly.
While Wikipedia aims to be an neutral, factual encyclopedia, some criticism exists over biases that may subtly influence article content depending on who is editing. To mitigate this, editors are encouraged to disclose conflicts of interest and support any controversial claims with citations from academic or otherwise reliable sources. Wikipedia also features various software tools to help coordinate, discuss, and log article changes among its community of editors. This includes article talk pages for public discussions, a sophisticated revision history feature, and oversight systems to guard against vandalism and disruptive behavior.
Impact and Reception
Since its creation in 2001, Wikipedia has grown exponentially to become one of the biggest and most popular websites in the world. It is currently ranked 7th in global internet traffic according to Alexa rankings. Studies have found Wikipedia to be as accurate as Encyclopedia Britannica and other expert-written encyclopedias for mainstream scientific topics, defying early skepticism about its open model. Its massive scope of articles has also made it a frequently used resource by students, researchers, and internet users worldwide for quick fact-checking and introductory information on countless topics.
While praised for its massive volunteering effort to build the largest compendium of human knowledge, Wikipedia still faces some ongoing challenges. These include the heavy technological requirements and manual labor needed to coordinate thousands of editors globally, concerns over the subtle influence of majority or vocal editor demographics on content, and ongoing issues of vandalism/trolling that must be reverted. Overall though, Wikipedia has achieved unprecedented success and reach as a globally crowdsourced public knowledge platform. It continues to grow and evolve through open technological and community innovations to become ever more comprehensive.
