Collaborative educational library

Wikibooks is a free online collection of open-content textbooks and manuals, hosted by the Wikimedia Foundation alongside Wikipedia.

Anyone can write or edit the educational materials, which cover subjects from cooking to computer programming: I found a decent calculus textbook on Wikibooks.
