Open textbooks are textbooks that have been funded, published, and licensed to be freely used, adapted, and distributed. These books have been reviewed by faculty from a variety of colleges and universities to assess their quality. These books can be downloaded for no cost, or printed at low cost. All textbooks are either used at multiple higher education institutions; or affiliated with an institution, scholarly society, or professional organization.

The Open Textbook Alliance is a nationwide coalition of student government leaders who are working to bring open textbooks to college campuses. Our goal is to reshape the textbook market by fostering a marketplace where open textbooks can compete with, and eventually replace, traditional textbooks. As open options become more widely used, the market will eventually reach a tipping point where the major publishing companies will be forced to compete on price and accessibility, or else step aside.

We strive to remove barriers, with easy-to-access, affordable, adaptable open course materials.
