This annual symposium, organized by the Schoenberg Institute for Manuscript Studies (SIMS) in partnership with the Free Library of Philadelphia, brings together scholars from around the world and across disciplines to present research related to the study of manuscript books and documents produced before the age of printing and to discuss the role of digital technologies in advancing manuscript research. Whether relying on traditional methods of scholarship or exploring the potential of new technologies, the research presented in each symposium highlights the value of the manuscript book or document in understanding our intellectual heritage.
