This collection consists of nineteen photographs showing many aspects of student life at Drexel in 1898-1899. It includes interior shots of the Main Building, the library in the Main Building, student boarding facilities, the Drexel Museum, the exterior of Boarding House Row, and University of Pennsylvania buildings. The photographs show library employees and students at work, Drexel president James MacAlister in his office, and art students painting in a studio. Also included with the collection is one folder of research notes compiled for an exhibit in 2005. The captions written on the photograph enclosures were not written by Castleman but rather were added later (possibly by Drexel library staff).
