The Personnel series is divided into two subseries: Individuals and Groups.

The Individuals subseries consists of portraits of individual employees. The materials are arranged chronologically. Nearly every individual is identified, although identifications are not consistent sometimes the full name is given, sometimes just the initials, and some include the person’s job title. Names of individuals are listed for each folder as they have been provided. Occasionally a person will appear twice within a folder. The images date from 1918 through 1958.

The Groups subseries is arranged chronologically and then alphabetically. The images are both group portraits as well as candid or informal snapshots. There is the occasional image of an individual and not a group. The images are of employees at work anniversary dinners, receiving awards or service pins, departmental staff portraits, outings, events, and parties. Employees pictured includes women and minorities. There is also an album of original photographs of the Army-Navy E awards. The images date from 1919 to 1960 with one group of images from 1911.
