Art and architecture are celebrated in works on the cathedrals, monuments, sculpture gardens, cemeteries, and architectural masterpieces of Italy, especially of the Lombardy and Piedmont regions. The Cathedral of Milan and the Certosa of Pavia are especially well represented. Exhibition catalogs of museums and galleries in Milan document the artistic culture of the nineteenth century, as do libretti and theater programs. Antiquities and Roman ruins are detailed in works on numismatics, inscriptions, and archaeological discoveries. The collection also has practical manuals and technical handbooks; biographies of artists; histories of art collections and museums, both private and civic; histories of art academies and guilds; and philosophical works on art, architecture, and aesthetics.
