The Institute of Art History Photo Library holds a series of copies of photographs held in the collections of Bernard Berenson at the Villa I Tatti, Settignano (Florence): 28,750 photographs, all black and white gelatin prints (10 x 10.5 cm) collected in 50 boxes, sorted alphabetically according to artist.

The collection was created thanks to a special agreement signed with the Villa I Tatti following the serious damage to the photographic archive of the Fondazione Cini during the flood of 4 November 1966.
