University libraries are well positioned to run or support OER production and publication operations. Many university libraries already have the technical, service, and policy infrastructure in place that would provide economies of scale for nascent and mature OER projects. Given a number of aligning factors, the University of Michigan (U-M) has an excellent opportunity to integrate Open.Michigan, its OER operation, into the University Library. This paper presents the case for greater university library involvement in OER projects generally, with U-M as a case study.
