Wikibooks (previously called Wikimedia Free Textbook Project and Wikimedia-Textbooks) is a collection of free books. It is one of many projects that are run by the Wikimedia Foundation. It is a wiki, which makes it possible for anyone to edit.

Some books are original, but others have started as text copied from other sources of free-content textbooks found on the Internet.

The CC-BY-SA license covers all the content that is in Wikibooks.

In February 2010, the Simple English Wikibooks was closed and locked due to anti-Simple-English users on Meta-Wiki misleading the Wikimedia Language Committee


Wikijunior is a subproject of Wikibooks that has 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 and Spanish. It is funded by a grant from the Beck Foundation.

Pages in Wikijunior will have the Wikijunior: prefix in front of the page's name.
