Librarians working in academic settings have taken different stances on providing access to materials assigned in courses. Although libraries have long offered course reserves, adding course-assigned materials to permanent library collections has been discouraged for a variety of reasons. A number of events and considerations—including COVID-19 campus shutdowns, growing online degree programs, increased support for student success, availability of open educational resources (OER), and new e-books licensing models that support multiple users—have made library provisioning of assigned materials, commonly referred to as textbooks, more mainstream. Despite differences in their scope, approach, and workflows, many library-led textbook affordability programs share the common goal of promoting equity.
