Books published by a number open publishers, such as OpenStax, BC Campus, Open SUNY, and more are aggregated in the OTL. Anyone can suggest a title be added to the library, but the book must meet these criteria.

  • Many of the textbooks in the OTL are reviewed by subject experts using a robust evaluation rubric. 
  • All textbooks are free to use, adapt, and distribute. Open textbooks can be downloaded for no cost, or printed inexpensively.
  • Textbooks can usually be downloaded in PDF format, as well as EPUB and HTML. Accessibility is enhanced with the availability of an EPUB version.
