List of Wikipedias
is a free multilingual wiki-based open-source online encyclopedia edited and maintained by a community of volunteer editors, started on 15 January 2001 as an English-language encyclopedia. Non-English editions followed in the same year: the German and Catalan editions were created on 16 March, the French edition was created on 23 March, and the Swedish edition was created on 23 May. As of , Wikipedia articles have been created in editions, with currently active, closed and 11 moved to Incubator.
The Meta-Wiki language committee manages policies on creating new Wikimedia projects. To be eligible, a language must have a valid ISO 639 code, be "sufficiently unique", and have a "sufficient number of fluent users".
Variations in editions
Wikipedia projects vary in how they divide dialects and variants. For example, the English Wikipedia includes most modern varieties of English including American English and British English. Similarly, the Catalan Wikipedia encompasses all Catalan variants, like Valencian, Balearic or France's Catalan; Spanish Wikipedia includes both Peninsular Spanish and Latin American Spanish; and the Portuguese Wikipedia includes both European Portuguese and Brazilian Portuguese. In contrast, some languages have multiple Wikipedias. For example, Serbo-Croatian encompasses four Wikipedia editions, Serbo-Croatian and three different standardized varieties.Additionally, some Wikipedia projects apply different approaches to orthography. For instance, the Chinese Wikipedia automatically transliterates between six standard forms: three using simplified Chinese characters and three using traditional Chinese characters. And rather than relying on transliteration, Belarusian has separate Wikipedia projects for the official Narkamaŭka and Taraškievica orthographies.
Wikipedia edition codes
Each Wikipedia project has a code, which is used as a subdomain of wikipedia.org. The codes mostly conform to ISO 639-1 two-letter codes or ISO 639-3 three-letter codes, with preference given to a two-letter code if available. For example, en stands for English in ISO 639-1, so the English Wikipedia is at en.wikipedia.org.Wikipedia editions
