Mission
The Open Book Project is aimed at the educational community and seeks to encourage and coordinate collaboration among students and teachers for the development of high quality, freely distributable textbooks and educational materials on a wide range of topics. The advent of the Internet and the World Wide Web are making collaboration among educators on a global scale possible for the first time. We want to harness this exciting technology to promote learning and sharing.
