Adopting a slightly different format to the previous catalogues in the series, this one is subdivided into four parts. The first two focus on books on architecture, the first composed of individual data files. The third focuses on the Italian Novecento and lists catalogues, monographs, theoretical writings, repertoires, manuals, and periodicals on architecture, furnishings, decorative arts, and design. The fourth section proposes a selection of books on garden design and landscaping. The contents of the last three sections are supplemented with a set of plates illustrating over half of the titles listed in the catalogue.
