In the years 1961-1972 Marie-Thirhse d'Alverny published in "Archives d'Histoire Doctrinale et Littiraire du Moyen Age 11 fascicles of a study of the codicological tradition of the Latin Avicenna. In these she identifies and describes more than 150 Latin manuscripts of the Avicennan corpus preserved in European libraries, thus laying the foundation for work later published in the "Avicenna Latinus series. These fascicles are photomechanically reprinted here, together with hitherto unpublished material concerning another 30 manuscripts compiled from Professor d'Alverny's papers by Simone van Riet and Pierre Jodogne. The compilers have also added a list of corrigenda as well as an index of manuscripts discussed and an index of names and works.
