This study explores how faculty members select and use the educational materials employed in their courses. The primary sample represents all teaching faculty across all types of degree-granting higher education institution in the United States. Two subgroups of faculty are called out for detailed examination: those teaching large-enrollment introductory level courses, and those teaching at minority serving institutions. The most common educational material employed in a course is the required textbook: faculty members typically choose one or more books that all students use throughout the course. Faculty also employ a wide range of other materials -- some optional, others required for all students. This study also examines an emerging distribution model typically called "inclusive access," which often goes by various names and has no single clear definition. The changes to higher education induced by the COVID-19 pandemic came amidst a time of considerable evolution in how publishers distribute and market their content, and how faculty discover, evaluate, and select course materials. New, digital-centric alternatives played a large part in supporting the massive teaching changes in Fall 2020. [For "Inflection Point: Educational Resources in U.S. Higher Education, 2019," ED616836.]
