"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 library currently includes 616 textbooks, with more being added all the time."

Introductory textbooks in most disciplines, peer-reviewed, openly licensed, 100% free. "OpenStax is a nonprofit educational initiative based at Rice University, and it's our mission to give every student the tools they need to be successful in the classroom. Review the textbook online, and if you decide to use it in your class, let us know. To access faculty-only materials, you can create an OpenStax account and request faculty access. Once we manually verify that you’re an instructor, you will have access to all faculty content. Include the textbook URL in your course materials, and from there, students can choose how they want to view the book."
