Fans and scholars of medieval illuminated manuscripts may enjoy BiblioPhilly, a new digital interface for the Bibliotheca Philadelphiensis project. This three-year project, which launched in 2016, has been digitizing 160,000 manuscript pages held by 15 libraries to "create the country's largest regional online collection of medieval manuscripts." The BiblioPhilly interface was made public in November 2018, and the project is due to be completed in the spring of 2019. Visitors to BiblioPhilly can search this repository of manuscripts by keyword and filter their search by facets such as book type, century, geographic origin, and more. Upon selecting a manuscript, visitors are treated to high-resolution, full-color images with an interactive page-turning interface, as well as descriptive metadata, additional images of its binding, and other information. Images and their metadata are also freely available to download under a Creative Commons license. The Bibliotheca Philadelphiensis project was funded by a grant from the Council on Library and Information Resources, and it was organized by the Free Library of Philadelphia, Lehigh University, and the Penn Libraries.
