Educational Resources Instructional Materials Copyrights Academic Libraries Research Universities Opportunities Shared Resources and Services Library Services Media Adaptation Adoption (Ideas) Material Development Open Educational Resources (OER) have saved students millions of dollars in textbook costs and greatly expanded access to a wide variety of educational materials for countless numbers of students and life-long learners. OER have also saved teachers time and effort by allowing them to reuse, modify, and build on materials developed by other teachers. After a brief discussion of OER and foundations of open licensing, this article presents a number of opportunities for libraries, particularly those situated at research universities.
