Over the last quarter century, a plethora of studies on literacy, reading, and writing in medieval Europe have contributed significantly to our understanding of medieval society and culture. Nevertheless the sheer number of these studies and their authorship by scholars in several different disciplines have obscured the relationships between these studies, their common themes and their differences. This essay seeks to survey this literature and its background, to explicate its contributions to the field of medieval history, and to suggest avenues for future study. It also reveals how approaches developed outside medieval studies were borrowed and adapted by medievalists, and how the study of literacy, reading, and writing in the Middle Ages has, in turn, influenced the work of ancient and modern historians.
