Wikibooks
Wikibooks is a wiki-based Wikimedia project hosted by the Wikimedia Foundation for the creation of free content digital textbooks and annotated texts that anyone can edit.
Initially, the project was created solely in English in July 2003; a later expansion to include additional languages was started in July 2004. As of October 2025, there are Wikibooks sites active for 78 languages comprising a total of 352,114 articles and 1,861 recently active editors. At primary stages it was called Wikimedia Free Textbook Project and Wikimedia-Textbooks.
The wikibooks.org domain was registered on July 19, 2003. It was launched to host and build free textbooks on subjects such as organic chemistry and physics, in response to a request by Wikipedia contributor Karl Wick. Three major sub-projects, Wikijunior, Cookbook and Wikiversity, were created within Wikibooks before its official policy was later changed so that future incubator-type projects are started according to the Wikimedia Foundation's new project policy.[clarification needed]
In August 2006, Wikiversity became an independent Wikimedia Foundation project.
Since 2008, Wikibooks has been included in BASE.
In June 2016, Compete.com estimated that Wikibooks had 1,478,812 unique visitors.
Wikijunior is a subproject of Wikibooks that specializes in books for children. The project consists of both a magazine and a website, and is currently being developed in English, Danish, Finnish, French, German, Italian, Japanese, Spanish, Arabic and Bangla. It is funded by a grant from the Beck Foundation.[citation needed]
While some books are original, others began as text copied over from other sources of free content textbooks found on the Internet. All of the site's content is released under a Creative Commons Attribution-ShareAlike license (or a compatible license). This means that, as with its sister project, Wikipedia, contributions remain copyrighted to their creators, while the licensing ensures that it can be freely distributed and reused subject to certain conditions.
