Looking for the program of the 48th Congress (2013)? It is now archived in ScholarWorks at WMU.
Congress sessions, which are 90 minutes long, are constituted as follows:
Sponsored Sessions are organized by learned societies, associations, and institutions. The organizers set predetermined topics, usually reflecting the considered aims and interests of the organizing group.
Special Sessions are organized by individual scholars and ad hoc groups. The organizers set predetermined topics, which are often narrowly focused.
General Sessions are organized by the Congress Committee at the Medieval Institute. Topics include any area of medieval studies, with individual session topics determined by the topics of paper proposals submitted and accepted.
