List of Wikipedias
is a multilingual online encyclopedia edited and maintained by a community of volunteer editors., Wikipedia articles have been created in 312 languages, with 302 active and 10 closed.
Wikipedia edition codesEach Wikipedia has a code, which is used as a subdomain below wikipedia.org. Interlanguage links are sorted by that code. The codes represent the language codes defined by ISO 639-1 and ISO 639-3, and the decision of which language code to use is usually determined by the IETF language tag policy. Wikipedias also vary by how thinly they slice dialects and variants; for example, the English Wikipedia includes most modern varieties of English, but does not include other related languages such as Scots or Anglo-Saxon, both of which have separate Wikipedias. The Spanish Wikipedia includes both Peninsular Castilian and Latin American Spanish; Malay Wikipedia includes a large number of Malay languages; and so on.
Differences between the ISO mappings and Wikipedia codes include:

Additionally, Wikipedias vary in orthography at times. Chinese Wikipedia automatically translates from modern Mandarin Chinese into five standard forms: Mainland China and Singapore in simplified Chinese characters, and Taiwan, Hong Kong, and Macau in traditional Chinese characters. Belarusian, however, has a separate Wikipedia for the 'normative' orthography and Taraškievica.
