In the fall 2022 semester, 434 students across eight Penn State campuses collectively saved tens of thousands of dollars as a result of faculty replacing commercial textbooks with a combination of open educational resources (OER) and resources licensed by Penn State University Libraries. With support from the University Libraries Open and Affordable Educational Resources Leads Grant Program, 34 faculty from the Penn State Abington, Beaver, Brandywine, Fayette, Greater Allegheny, Lehigh Valley, Shenango and University Park campuses collaborated with librarians at their campuses to identify open and library-licensed course materials that would meet their course outcomes and their students’ learning needs, while also making the course materials free for students.
