Source of acquisition--The Office of Public Affairs Photograph Collection is comprised of several different accessions.

Source of acquisition--The first (accession 2000-006) was transferred from the University Photographer and dated circa 1947-1983. The negatives and slides resided in two metal filing cabinets. The original subject divisions provided by Manny Warman, University Photographer, 1947-1983, were retained. The negatives were left in their original paper sleeves, but ultimately re-boxed into archival negative boxes.

Source of acquisition--The second accession (2003-034) included photographs taken by Joe Pineiro, University Photographer, 1983-1998 and those taken by freelance photographer Eileen Barroso, 1985-1998. The negatives for these images were transferred in their negative cabinets, arranged in alphabetical order. These were also kept in their original storage sleeves but re-boxed into archival negative boxes. Accessions 2000-006 and 2003-34 now comprise Series II of this collection.

Source of acquisition--Color slides (now found in Series III of this collection) were received in accession 2002-035. These were removed from their original binders, filed, and re-boxed. Color slides found in accession 2001-052 were added to these boxes.

Source of acquisition--A separate accession (2001-052) of photographs depicting 1968 student protests on campus is housed in binders for ease of access. Related protest negatives from earlier accession 2000-006 were added to binders. These were received on December 28, 2001 from Roger Hackett in the Office of Public Affairs (OPA), who had received them from Suzanne Trimmel who also worked in that office. This accession now comprises Series IV of this collection.

Source of acquisition--Negatives and slides from the accession 2003-046 were used by the Columbia University Record, a publication of the Office of Public Affairs. Most negatives were taken by photographer Amy Callahan and date from 1997-1998. For purposes of storage, corresponding contact sheets were separated from negatives and housed within the Historical Photograph Collection (UA#0003). All negatives are 35mm format and were re-boxed. These negatives can now be found in Series II of this collection.
