ANSWER:

The Editorial, Graphics & Publishing Services unit of the Department of Materials Management maintains a digital archive of all the photographs taken by long-time staff photographer, Mr. Bill Mills (retired 2013). This archive is maintained on a dedicated server with image-archival software (Aperture) at the Lincoln Center printing facility. It includes more than 200,000 digital images produced from 1999 to 2013. The images are searchable by date and, for more recent files, by imbedded meta data.

Photography prior to 1999 was produced with film and archived as prints with negatives, 35mm slides, and contact sheets. These materials are housed in 22 file cabinets in CESC. The archive dates back to 1968. The materials are stored in folders marked with information concerning image content and date.
