The Institut de recherche et d’histoire des textes (IRHT) in Paris makes available a series of specialized electronic tools on medieval manuscripts, among which is Bibale, a database that aims to trace the provenance of medieval manuscripts and to reconstruct historic book collections from the medieval and early modern periods. This article explains the history, scope, and present state of this database and its links with several other tools, among which are the image repository Bibliothèque virtuelle des manuscrits médiévaux (BVMM) and the Biblissima project that is working on interoperability of a series of French digital humanities projects concerning manuscripts and early printed books.
