"OER are teaching, learning, and research resources that reside in the public domain or have been released under an intellectual property license that permits their free use and re-purposing by others. Open educational resources include full courses, course materials, modules, textbooks, streaming videos, tests, software, and any other tools, materials, or techniques used to support access to knowledge."

- University of Melbourne: Free Online Resources for Teachers
- The University of Oklahoma: Open Educational Resources
- University of Illinois at Urbana-Champaign: What are OER?
- Lansing Community College Library: Open Education Resources
- Belk Library and Information Commons, Appalachian State University: K-12 Open Education Resources
