This database, published in collaboration with the IRHT, will be an answer to the challenge raised by the proliferation of the current bibliography, by focusing on two criteria: the speed of the data extraction and the analytical quality of the records. The database provides an up-to-date bibliography with very little timelag. It is a bibliography about late medieval authors and texts, and includes the manuscripts cited in catalogues by library collections, by genres, or by authors as well as in editions or other studies.
