Mapping Manuscript Migrations is a new two-year project funded by the Trans-Atlantic Platform in the fourth round of its Digging into Data Challenge. The project is a collaboration between four international partners: the University of Oxford, the University of Pennsylvania, the Institut de recherche et d’histoire des textes (IRHT) in Paris, and Aalto University in Helsinki. The project aims to combine data from various different sources to enable the large-scale analysis of the history and provenance of medieval and Renaissance manuscripts.
