The Personal Files series contains materials about Kennan's career, as well as his personal life. The majority of the series is composed of newspaper articles, either clippings or arranged in scrapbooks, about Kennan which cover his entire career at the State Department and at the Institute for Advanced Study, as well as his opinions on current events and his retirement. Also included are recordings of interviews, lectures, conferences, and television programs by or about Kennan, his appointment calendars from 1965 and 1970-2000, papers for classes he taught at Princeton University, and materials he provided to his official biographer John Gaddis, notably the FBI's file on Kennan. Other materials include photographs, awards and honorary degrees, topical files of articles Kennan collected, and files on Kennan's travels.

Series 2: Examinations Arranged by Subject, 1833-1998 consists primarily of examinations for Princeton undergraduate courses. It also contains a small number of exam schedules, graduate examinations, and instructions.

The Departments and Centers series consists of the records of the various departments (and in later years, research centers) which fall under the authority of the School of Engineering. As engineering has progressed rapidly over the course of the 20th century, many of these departments have undergone changes in title, mergers, or been disbanded completely. For the purposes of description, the names used here reflect the name of the Department or Center at the date of the most recent records found in the corresponding subseries.

Contains photographs filed by subject.

The Clubs and Organizations series documents the many clubs and organizations that members of the Princeton University community have created throughout Princeton's history. Though most clubs are founded, run, and consist only of students, some clubs are run just by faculty and staff or include all three. Many of the files only contain but a few clippings that give just a slight understanding of those clubs and organizations, although others are more richly documented.

Consists of the writings, correspondence, photographs, and scrapbooks of Louise Selina Bonynge Maxwell.

The Administration series consists of photos of Princeton administration.

The Faculty series consists of photos of Princeton faculty.

Series 4: Faculty and Staff includes faculty meeting minutes; basic files the department maintained on faculty members (which may include clippings, correspondence, curriculum vitae, and photographs); as well as the more extensive files of longtime faculty members such as A.F. Buddington, B.F. Howell and William Taylor Thom. Files on Arnold Guyot primarily contain research about Guyot; other faculty files may have been maintained by the faculty themselves and include material such as correspondence (some personal); publications; course and lecture materials including examinations; diaries and field notes; biographies and bibliographies; faculty contracts and recommendations; photographs; and an autograph book as well as letters kept primarily for autographs. William Bonini's files include a box of his gravity journals, notebooks of field observations.

The Administrative series contains documents generated by or written about the governance of the school of Public and International Affairs throughout its existence as well as planning documents which predate the School itself.

This series consists of files on the faculty, faculty meetings, faculty procedures and rules, and benefits, as well as other assorted topics related to the University faculty.

Series 3: Maps and Surveys, 1849-1981 contains originals and copies of maps and surveys of Princeton University land that were intended to represent the campus and other University lands as they existed. This is in contrast to maps, plans and surveys in the records of the Office of Physical Planning, which were created as part of the planning and development process and may or may not represent what actually existed. In addition to professionally produced and published maps, this series also contains several student surveys of portions of university land from the early 20th century, possibly created as part of an academic course.

The Lectures series documents some of the various lectures given at Princeton over the years. Lecture information is filed by the name of the lecture series, when applicable and known, or otherwise by the name of the lecturer. Colloquia and panel discussions are filed in Series 12 (Conferences) or according to the subject of the event.
