The Wikipedia Library

Partnering the world’s top publishers with Wikipedia

Schedule a call to learn more

Wikipedia is one of the most widely used sources of information on the internet, with more than 62 million articles in over 300 languages. All of the information on Wikipedia is curated by a global community of volunteer editors. These editors compile and share knowledge on notable subjects from reliable sources — such as books, newspaper articles, and peer-reviewed journals — in accordance with Wikipedia’s editorial policies, to ensure knowledge remains fact-based.

Today, however, many of the world’s most reliable sources can only be accessed through a paid subscription. Through partnerships with more than 100 of the world’s top subscription-only databases, The Wikipedia Library, a project of the Wikimedia Foundation, gives Wikipedia’s most active editors access to knowledge resources in over 30 languages.

Wikipedia editors use this information to add trustworthy knowledge to the site. Importantly, editors add links to their sources, which brings more visibility to partners’ quality research materials.

Wikipedia: A research resource

Every month, people around the world view Wikipedia more than 15 billion times and read its articles in more than 300 languages. Students and researchers often refer to Wikipedia as a starting point and for fact-checking. They discover new academic books, articles, and journals from publishers through the citations used on Wikipedia.

In 2023, The Wikipedia Library was used to add over 165,000 new citations to Wikipedia articles in over 100 languages. This knowledge benefits readers by offering trustworthy information to the world’s largest online knowledge source. It also benefits the publishers who partner with The Wikipedia Library, in that they increase the visibility of their resources and refer readers who are looking for more information.

How The Wikipedia Library works

Only the most dedicated Wikipedia volunteers can access The Wikipedia Library. To gain access, volunteers are required to have made more than 500 edits on Wikipedia and other Wikimedia projects over a minimum six-month period.  Whenever an editor requests content from The Wikipedia Library, our team does a real-time check to verify that they still meet the requirements. Additionally, partners can control access to their content using proxy-based access, coupon codes, emails, or other methods.
