In November, 1994, the Special Collections Library completed a two-year project to provide greater access to the Guido Mazzoni Pamphlet Collection. Acquired in 1948, this collection comprises over 49,000 pamphlets, newspapers, clippings, small volumes, librettos, epithalamia, and broadsides. Imprints range from the late sixteenth century to 1943. It is one of the largest private Italian libraries of its kind in the United States. Many of its pieces are very rare and difficult to find in the United States and even in Italy. To make this large collection more accessible to scholars, each item has been classified under one of thirty-one sub-collections, each with its own Library of Congress subject heading. Collection-level bibliographic records for the Guido Mazzoni Pamphlet Collection and the thirty-one subject areas are also located in the Duke Libraries online catalog. For more in-depth research, interested scholars may wish to consult an item-level database, which contains a brief bibliographic record for each pamphlet in the collection. The website does not currently contain digitized versions of the pamphlets themselves.
