The Bodleian's incunable catalogue describes the Library's fifteenth-century western printed books to the same standards expected in the best modern catalogues of medieval manuscripts. It records and identifies all texts contained in each volume, and the detailed analysis of the textual content is an innovative feature. Further information about authors, editors, translators, and dedicatees is given in an extensive index of names, complete with biographical and other information; this index will be of interest to textural scholars from the classical period to the renaissance. The detailed descriptions of the copy-specific features of each book (the binding, hand-decoration and hand-finishing, marginalia, and provenance) form another important contribution to scholarship. The provenance index will be of great value to all those interested in the history of the book from the 1450s to the present day.
