With its more than 40 million articles in 301 different languages, Wikipedia is one of the largest human collaboration efforts in history. One of the main pillars on which this wish to bring together the sum of all knowledge is based is the achievement of a neutral space. However, several studies suggest that the site suffers from a persistent gender bias as regards both content and the composition of its community. An analysis of the gender gap in the Spanish-language version of Wikipedia by an interdisciplinary team at the UOC has revealed that only 11.6% of its registered editors are women.
