The Student Photograph Albums Series of the Historical Photograph Collection (HPC) contains 180 photographic albums created by Princeton University students. These albums, along with the other photograph collections in the University Archives, help document the experiences of students, faculty, and staff at Princeton University. The albums date from 1851 to 1995, although the bulk date from the 1860s to the 1910s. New accessions are added regularly to the collection.

The Class Records consist of a diverse set of materials documenting the history and activities of Princeton University classes during their time as undergraduates and as alumni. In the collection are correspondence, newsletters, publications, photographs, and memorabilia, all of which pertain to a particular Princeton University graduating class and its members.
