Open access textbooks (OATs) and educational resources (OERs) are being lauded as a viable alternative to costly print textbooks. Some academic libraries are joining the OER movement by creating guides to open repositories. Others are promoting OATs and OERs, reviewing them, and even helping to create them. This article analyzes how academic libraries are currently engaged in open access textbook and OER initiatives. By drawing on examples of library initiatives across the United States, the author illustrates how libraries are facilitating the adoption and implementation of these affordable resources.
