www.Wikibooks.com – Free Textbooks Resource
Looking for free textbooks? Are you really going to spend $100 or more for a textbook when you can get the same or similar information for free? At WikiBooks you can get a huge collection of open-content textbooks that anyone, including you, can edit. If you have knowledge of something you want to share you can contribute with WikiBooks by editing pages or creating new pages.
You can also contribute by making donations. The site features textbooks, annotated texts, instructional guides, and manuals. These materials can be used in a traditional classroom, an accredited or respected institution, a home-school environment, or for self-learning. As a general rule, most non-fiction books are not suitable for inclusion as they are not instructional. Wikibooks is not a dictionary, it is not a thesaurus, and it is not a free wiki host or webspace provider, or a vehicle for propaganda and advertising. Browse through departments such as natural sciences, social sciences, computing, humanities and arts, special groups, or categories such as geography, law, mobile phones, society, food & drink, games, etc. and get the book you are looking for. Also browse books alphabetically, by Library of Congress classification, or by Dewey decimal classification. The central place to ask questions or discuss ideas is the Staff Lounge (this is the equivalent to Wikipedia’s Village Pump). WikiBooks has two mailing lists for general users and administrators available in a number of formats, via a web archive, by email, and others. Teachers can also consider making the development of a textbook a class project. Students learn not only the subject matter at hand, but also the art of collaboration, and they establish contacts with other students from around the world.
