GUIDE: Michel, S. P. Repertoire des ouvrages imprimes en langue italienne au XVII siecle. This is a microfilm set of a selection of 17th century books written in Italian about all subject areas. The set is based on the Michel bibliography but also contains other titles. This is a continuing project, with additional reels received periodically. Most of the titles have been cataloged with over 2,800 individual titles in CRLCATALOG.
