- College Open Textbooks (COT)
College Open Textbooks (COT) is a project of the Silicon Valley Education Foundation and the Open Doors Group. The COT Collaborative is collection of colleges, governmental agencies, education non-profits, and other education-related organizations that are focused on the mission of driving awareness, adoptions, and affordability of open textbooks. Our focus is on community colleges and other 2-year institutions of higher education and the first two years (lower division) of 4-year institutions. Some of our activities also apply to K-12, upper division, graduate school, and life-long learning. An open textbook is an integrated course-associated learning tool that is in the public domain or has been open-licensed by the copyright holder to permit re-use without the necessity of asking permission of the copyright holder. Open textbooks are free or inexpensive on the web and modestly priced for downloads, use on eReaders, or in bound format.
