Overview

Wikibooks is a global collection of openly licensed textbooks, manuals and learning resources created and maintained by volunteers. It is designed as a place where people can write, adapt and share instructional content that anyone may read and reuse. Entries range from introductory tutorials to more advanced subject treatments and are usually grouped into book-sized collections or modules.

Organization and characteristics

The project is one of the online initiatives supported by the Wikimedia Foundation. Content on the site is published under a copyleft licence: the Creative Commons Attribution-ShareAlike (CC BY-SA), which allows copying, adapting and redistribution provided that the same licence and attribution are preserved.

Wikibooks uses a wiki model — contributors can edit most pages directly — so material evolves through collaboration and peer editing. In practice this produces a mix of original works and texts adapted or imported from other free-content sources. Materials may be translated into multiple languages, reorganized into chapters, or converted for offline use.

History and development

The project began as an effort to assemble free textbooks and educational materials in a single, editable platform. Over time it expanded to include how-to guides, problem sets and specialized manuals. Like many volunteer-run knowledge projects, it has experienced shifts in activity, organizational changes, and occasional policy updates aimed at improving quality and licensing clarity. One notable administrative action was the closure and locking of the Simple English Wikibooks edition in February 2010, a decision recorded on project pages and notices (Simple English Wikibooks closure).

Uses and examples

  • Students and educators use Wikibooks as a free supplementary textbook source or for curriculum development.
  • Self-learners consult tutorials and language lessons for structured study.
  • Editors and subject enthusiasts compile collections to document practical skills, programming languages, and academic topics.

Strengths, limitations and notable facts

Wikibooks' strengths lie in openness, collaborative revision and permissive reuse. Its limitations include variable quality and uneven coverage: some subjects have comprehensive guides while others are incomplete. The site interoperates with other Wikimedia projects and supports export and printing tools, enabling contributors and readers to create downloadable or printable editions.
