The "Iter Italicum" serves as a useful reference work for scholars in the history of philosophy, the sciences, classical learning, grammar and rhetoric, Neolatin literature, historiography of the theory of the arts and of music and related subjects. By scanning the volume or through this index, scholars will be able to find source material for individual writers as well as for certain subjects, problems or themes. By indicating for each manuscript its location and shelf-mark, scholars will find it easier to order microfilms or to pursue more detailed studies of some of the manuscripts listed. The volumes should also prove useful for librarians as a reference for the holdings of their own or other libraries.

This interdisciplinary handbook provides extensive information about research in medieval studies and its most important results over the last decades. The handbook is a reference work which enables the readers to quickly and purposely gain insight into the important research discussions and to inform themselves about the current status of research in the field. The handbook consists of four parts. The first, large section offers articles on all of the main disciplines and discussions of the field. The second section presents articles on the key concepts of modern medieval studies and the debates therein. The third section is a lexicon of the most important text genres of the Middle Ages. The fourth section provides an international bio-bibliographical lexicon of the most prominent medievalists in all disciplines. A comprehensive bibliography rounds off the compendium. The result is a reference work which exhaustively documents the current status of research in medieval studies and brings the disciplines and experts of the field together.
