A large album of prints by photographer Antoin Sevruguin, likely dating from his early career in Iran in the 1870s and 1880s. The collection also includes a number of loose, unbacked prints, many duplicating the photographs in the album. Roughly half of the mounted prints have English handwritten captions.

This collection is comprised of digital surrogates previously available on the 90 rolls of microfilm described in the NARA publication M1903. These digital surrogates reproduced the records of the Georgia staff offices and subordinate field offices of the Bureau of Refugees, Freedmen, and Abandoned Lands, 1865–1872. These records consist of bound volumes and unbound records, containing materials that include letters and endorsements sent and received, monthly reports, registers of patients, orders and circulars issued and received, and other records relating to freedmen's complaints and contracts.

The Leo Castelli Gallery records measure 215.9 linear feet and 0.001 GB and date from circa 1880-2000, with the bulk of the materials dating from the gallery's founding in 1957 through Leo Castelli's death in 1999. The major influence of dealer Leo Castelli and his gallery on the development of mid-to-late twentieth century modern art in America is well-documented through business and scattered personal correspondence, administrative files, exhibition files, extensive artists' files and printed materials, posters, awards and recognitions, photographs, and sound and video recordings. Also included are records for the subsidiary firms of Castelli Graphics and Castelli/Sonnabend Tapes and Films.
