This document discusses the high costs of textbooks and how open educational resources (OER) can help increase college affordability and student success. It notes that textbook costs can be a barrier to student access and success, with many students deciding against buying required textbooks or taking certain classes due to expense. OER, which are teaching materials that are free to use and distribute, provide a solution by reducing costs to zero while maintaining or improving learning outcomes compared to traditional resources. The document advocates for increased adoption of OER to save students billions in costs annually while maintaining educational quality.
