Open Educational Resources (OER) are high-quality teaching, learning, and research resources that reside in the public domain or have been released under an intellectual property license, such as a Creative Commons license, that permits their free use and repurposing by others, and may include other resources that are legally available and free of cost to students.
S.B. 1359 states Zero Textbook Cost (ZTC) course materials “may include open educational resources, institutionally licensed campus library materials that all students enrolled in the course have access to use, and other properly licensed and adopted materials.”
