This document summarizes a presentation on advocating for open educational resources (OER) on campus. It discusses the high costs of textbooks for students and rising tuition as problems that OER can help address. OER are defined as educational materials that can be freely used, adapted, and shared. The benefits of OER discussed include improving access and equity, allowing customization of materials, and enabling non-disposable and student-produced work. Suggested advocacy strategies include gathering data, advocating to faculty, asking for training and inclusion in the library, and forming a campus OER working group.
