Wikibooks (previously called Wikimedia Free Textbook Project and Wikimedia-Textbooks) is a wiki based Wikimedia project hosted by the Wikimedia Foundation for the creation of free content textbooks and annotated texts that anyone can edit.

In September 2015, estimates that Wikibooks had 2,102,708 unique visitors.[2]


The domain was registered on July 19, 2003 (2003-07-19),[3] and launched in response to a request made by Wikipedia contributor Karl Wick for a project to host and build free textbooks on subjects such as organic chemistry and physics. Two major sub-projects, Wikijunior 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. In August 2006, Wikiversity became an independent Wikimedia Foundation project.


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 and Arabic. It is funded by a grant from the Beck Foundation.

Book content[edit]

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-Share Alike 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.

Wikibooks differs from Wikisource in that Wikisource collects exact copies and original translations of existing free content works, such as the original text of Shakespearean plays, while Wikibooks is dedicated either to original works, significantly altered versions of existing works or annotations to original works.

The project is working towards completion of textbooks on numerous subjects, which founders hope will be followed by mainstream adoption and use of textbooks developed and housed there.
