The Archive’s collections have grown organically in keeping with its evolving program. In addition to its core collection of student work, the Archive maintains a collection of photographs and records documenting the School’s exhibitions and related publications, an extensive blueprint collection of major works of architecture, a collection of thousands of 4 x 5 glass lantern slides formerly used by Cooper Union faculty to teach History of Architecture and Town Planning, and an assortment of photographs, negatives, and maps relating to the history of New York City’s waterfront. Recent acquisitions include a collection of New York City postcards donated by Joseph Covino (1999 – 2003) and a collection of travel photos taken by architect Stanley Prowler (2006).

Other photographic material housed in the Archive include design studio candid photos dating back to the 1890s and images of the Archive’s publications and special projects.
