VisColl is a system for building models of the physical collation of manuscripts, and then visualizing them in various ways. The project is led by Dot Porter at the Schoenberg Institute for Manuscript Studies at the University of Pennsylvania and Alberto Campagnolo at the Université catholique de Louvain (Louvain-la-Neuve, Belgium), in collaboration with the University of Toronto Libraries and the Old Books New Science lab. This video gives a background to the project and talks through how to use the project software.
