The Nat Clymer Photographic Collection consists of nearly 14,000 images, primarily color 35mm slides and negatives, medium format [6cm X 7cm] color and black & white negatives & color transparencies, black & white contact sheets, as well as digital files. The photographs span Clymer's career as a contract photographer for the university, a period spanning the early portion of the 1980s and running through the early 2000s.

The collection offers a vivid portrayal of the University's campus through portraiture of buildings, faculty, students, and alumni engaged in a wide variety of activities. Many of the photographs in the collection were taken by Clymer on different assignments as a contract photographer, including assignments with the Advanced Technology Center for Photonics and Optoelectronic Materials (P.O.E.M.), the Development Office, the Princeton Materials Institute, and the Princeton Alumni Weekly, the latter of which comprises the bulk of the collection.
