Wikibooks

Wikibooks is a Wikimedia Foundation project that hosts free, open-content textbooks and manuals contributed by volunteers. It provides a growing library of educational materials across many subjects that anyone can read, edit, or contribute to. The project is designed to support teaching and learning with openly licensed content and runs on the same MediaWiki software used by Wikipedia. Wikibooks operates in many languages through separate language editions managed by community volunteers.

The collection covers topics such as mathematics, science, computing, humanities, languages, and more. Books may be complete textbooks or modular courses built from lessons and exercises, and pages are organized with chapters, sections, and navigation aids to guide learners. Materials are intended to be instructional rather than encyclopedic, with quality control guided by community guidelines, talk pages, and peer review processes.

Licensing and editing: All content is freely available under open licenses, primarily Creative Commons licenses, with some older material released under the GNU Free Documentation License. Anyone can create or edit books, subject to project guidelines and review by other editors. Contributors are encouraged to cite reliable sources and to avoid original research, aiming for clarity and accessibility for a general audience.

Relation to Wikimedia ecosystem: Wikibooks is part of the Wikimedia Foundation’s family of projects, alongside Wikipedia and Wiktionary. It supports global collaboration through language communities and aims to provide a free, adaptable library of textbooks that can be read online or downloaded and reused in classrooms or independent study.
