Yes! Both Cool4Ed and Open Oregon share what OER instructors are using. Open Oregon is limited to Oregon colleges and Cool4Ed is limited to CCC, CSU, and UC. Cool4Ed's "Faculty Showcase" and "Course Showcase" both give valuable insight into OER use around the state by providing evaluations of both quality and accessibility, and a general look into what other instructors are using. And remember, the Open Educational Resources movement is all about sharing, so feel free to reach out to other instructors at other instructions all over the country (and their libraries!) and ask them about their OER adoptions.
In addition, the California Community College Chancellor’s Office has created the Vision Resource Center, which has a section where all of the Zero Textbook Cost Degree Grantee colleges have uploaded the materials their courses used to develop the degree pathway.
