BiblioPhilly is the Bibliotheca Philadelphiensis project, which has been organized through the Philadelphia Area Special Collections Consortium (PACSCL) and funded by the Council on Library and Information Resources (CLIR). BiblioPhilly aims to digitize over 450 medieval manuscripts from 15 different institutions in the Philadelphia area. The project started in April 2016, and will finish in March 2019. The project PI is Lois Black, from the Lehigh University Special Collections, and co-PIs are Janine Pollock from the Free Library of Philadelphia and Dot Porter from the University of Pennsylvania Libraries, with invaluable assistance from Laura Blanchard at PACSCL. The digitized manuscripts are hosted on OPenn, which is a service of the University of Pennsylvania Libraries.
