Today the photo archive contains various resources of photo types, consisting of negatives on slab and film, and positives on paper, and in transparency in digital format. Among the most interesting pieces that it preserves, the Baccani Collection, the Collection of Fine Arts and the Historical Collection Bardini, are the ones that stand out. Donated to the City of Florence in 1898 by photographer Joseph Baccani and later enlarged by additional acquisitions, the eponymous collection is comprised of 300 slabs and 4 albums that portray the appearance of the city during the demolition of the old center which began in the late nineteenth century. The Fine Arts Collection documents the pieces made by the municipal offices in the twentieth century on the monumental buildings corporation. The Historical Collection Bardini, recovered in 1993 and still in the process of reorganization, consists of about seven slabs from the private archive of the antiquarian and collector, Stefano Bardini. From the late twentieth century, there are regularly carried photographic campaigns to boost Photo Archive and documentation of works of art of the civic museums. The photographic collection, whose overall size is estimated at around 112,000 assets are currently being catalogued.
