Fifteen years after it was launched, the free online encyclopedia Wikipedia is the world's seventh most popular website and now includes more than 38 million articles in 289 languages.
It may sound expansive, but the site has come under criticism for not covering all subjects, regions or issues with equal depth.
The bias has been blamed on those who write and edit the website; around 30,000 volunteers from around the world.
"There is systemic bias," said Aral Balkan, a digital rights activist with ind.ie .
"[It's] Western, white bias. About 90 percent of the editors of Wikipedia are male, so that's a problem we need to fix."
Wikipedia has been working to increase the diversity of its content and contributors through outreach programmes such as edit-a-thons at universities and museums and by trying to appoint more women administrators, but the site has yet to see any significant change.
"When the world's most important information resource is something that people put together on nights and weekends, that limits Wikipedia's projects to just the things that can be accomplished in those particular time windows and with that kind of commitment," said digital consultant William Beutler from Beutler Ink
