Jimmy Wales and Larry Sanger founded Wikipedia, a multilingual internet encyclopedia. The content of the encyclopedia is shared under a free and open license of the Creative Commons. Volunteer contributors from around the world participate in the creation of Wikipedia entries. Wikipedia’s precursor was the Nupedia web encyclopedia, to which, unlike Wikipedia, only experts were allowed to contribute. At the beginning of 2023, Wikipedia contained articles written in 331 languages.
