Since College Open Textbooks was created in 2008, the OER landscape has changed significantly.  Open textbooks have proliferated and there are now a growing number of curated repositories sponsored by various publishers, government entities, and university systems.  Maintaining a comprehensive listing of open textbooks is becoming less viable, and it’s clear that the successor to our current listings is an open textbook search engine.

College Open Textbooks has assembled a team to create a prototype search engine.  We’re partnering with several curated repositories, and our long-term plans are to productize the search engine and search as many repositories as possible.  If you represent a repository that would like to join this effort, or would otherwise like to become involved, contact us at
