College Open Textbooks (COT) is one of the premier resources for locating and adopting open-licensed textbooks. Each year, many thousands of educators, administrators, and students visit COT to make use of our extensive listings.

COT offers:

  • Over 700 titles, curated specifically for two-year colleges—but also appropriate for many lower-division courses at four-year colleges. This means COT can potentially benefit millions of students.
  • A comprehensive catalog of links to resources hosted by a wide range of online repositories and other sites.
  • Peer reviews of selected titles.  Our peer reviews follow a structured format that includes numeric ratings for five specific criteria as well as commentary.
  • Success Stories by authors, adopters, and students.  Our growing library of video testimonials highlights the powerful advantages of open textbooks, and encourage all educators to adopt.

Since 2008, College Open Textbooks has focused attention on two-year colleges, a vital segment of higher education that was once underserved by the open-education community. It is also proving an invaluable service to educators who wish to produce open textbooks.
