Since 2008, College Open Textbooks has provided the most comprehensive listing of open-licensed textbooks on the web.  Our mission is to promote the creation and adoption of open textbooks, thereby making higher education more accessible and affordable to all students.  Our extensive listings currently include nearly 800 books.  We have traditionally focused on textbooks for two-year college and lower division four-year college courses, but our listings include books appropriate for both advanced high school and upper division college courses, as well.

Originally conceived as a collaborative, College Open Textbooks was supported by generous grants from the William and Flora Hewlett Foundation and and enjoyed from partnerships with many leading educational organizations, including AcademicPub, Benetech Bookshare, Bridgepoint Education, Bronx Community College, California Community Colleges Chancellor’s Office, Carnegie Mellon University, Community College Consortium for Open Educational Resources, Flat World Knowledge, Florida Virtual Campus, Foothill-De Anza Community College District, Houston Community College, Institute for the Study of Knowledge Management in Education (ISKME), League for Innovation in the Community College, Link-Systems International, Macmillan DynamicBooks, MathScore, MentorCloud, MERLOT, Open Assembly, Open Education Resources Center for California, OER Commons, Rice University Connexions, Silicon Valley Education Foundation, SoftChalk, Tacoma Community College, Textbook Media, THiNKaha, Virtual Ability, and Words & Numbers.

From 2010 to 2015, College Open Textbooks was administered by Open Doors Group, a non-profit under the fiscal authority of the Silicon Valley Educational Foundation.  Today we are a project of COT Education, a registered 501(c)(3) corporation whose mission is to create and support programs that increase access to affordable lifelong learning for everyone.

An all-volunteer organization, College Open Textbooks welcomes contributions of money, time, and talent to facilitate it’s continuing mission.
