The Admission Office has determined who should be allowed to enroll as undergraduates at Princeton University since 1922. The actual composition and the desired composition of each class have been contentious campus issues since the introduction of selective admission. The debates over the value of recruiting and admitting alumni sons, war veterans, athletes, disadvantaged students (especially racial minorities), and women are reflected in the records of the Admission Office. This collection includes a number of reports and minutes, some of which are restricted, news clippings and releases about Princeton admission, historical materials, and a series of Admission Office publications.

There are a few letters concerning Nazi "Judenpolitik" (Jewish policy), some regarding arrests and camp conditions, others concerning scandalous associations with Jews. Military concerns are few and interspersed throughout. The majority of the material, mostly directed to Hitler, consists of wishes of health, happy birthdays, thank you's.
