Series 1: Records of Men consist of records of individual Princeton University students who served in the military from the Class of 1943 through the Class of 1949. There are single cards for each individual on which is noted biographical information, military rank, home address, service address, and other related information. There are also folders for individuals which include correspondence between Princeton University faculty and staff of the War Service Bureau office, as well as other materials relating to that student's class. For the Class of 1943 there are only cards, but for the Class of 1944 through 1949 there are individual folders for most men. The records are arranged chronologically by class, and alphabetically within each class. In general, the cards appear at the beginning of the chronological run.

Series 2: Subject Files are arranged alphabetically by subject and consist of the office files of the War Service Bureau. A great deal of the material is routine, but included here are the class business files and corresponding secretary files, as well as issues of Tiger Tales, the newsletter published by the Bureau, and files on students who were deceased, prisoners of war, wounded, or missing in action.

Series 3: Questionnaires (1944-1949) are arranged chronologically by class, and alphabetically within each class. The questionnaires consisted of a series of questions and categories for academic and personal information.
