The General series contains documents, clippings, and correspondence about each decade in Princeton's history from its founding until the present. The series consists of material that can neither be filed in any one other series nor in the chronologically arranged portion of the historical subject files. The files of Keeper of Princetoniana Frederic Fox, for example, include his notes on various aspects of Princeton life and history. Campus maps and general campus views can also be found here. Themed campus tours include views of Princeton in 1865, as well as tours focusing on trees and gargoyles.

Series 7: Secretaries of the University, is divided into several subseries, one for each individual to hold the office of secretary in order of their service.

Series 2 contains charters and bylaws and facsimiles of the same.

The first volume (1748-1796) is a gold mine of information about the personalities and activities of the young College of New Jersey. As these minutes date from the very beginning of the College, they address the multitude of issues and problems the trustees initially addressed. It was the era of the group decision, with the entire Board involved in solving every type of problem at their infrequent (two or three times a year) meetings. This volume is contained in two forms: the original volume (which does not circulate) and a typed transcript in two parts.

Series 1, Program Records, 1748-present, contains commencement, class day, and Service of Remembrance programs; pamphlets; schedules; valedictory and salutatory addresses; and newspaper clippings.

Series 1: Correspondence and Personal Material comprises the most voluminous series in Gillett Griffin's papers. Griffin was a prolific correspondent who often created several drafts of his letters and illustrated their salutations. Griffin filed correspondence in several different alphabetical runs. Some correspondence was also unfiled. The bulk of the letters were received by Griffin, but drafts or copies of his own letters are also present.
