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.

Consists of correspondence, documents, ledgers, photographs of the Meteor Crater (Ariz.) site, and printed matter of Barringer (Princeton University Class of 1879). The correspondence contains letters which deal with scientific and business activities in mining and meteorology, including those of several companies which Barringer founded or developed, such as the Hanover Bessemer Iron and Copper Company, El Palmarito Leasing Company, the Texas Iron Association, and the Meteor Crater Exploration Mining Company (general manager, George M. Calvocorresses, a major correspondent). The collection reflects Barringer's accomplishment in being the first to advance the theory that Meteor Crater was caused by the fall of a meteoric cluster, probably a small comet. There are a number of photographs, including over 100 cyanotypes and 6 lantern slides, mainly concerned with illustrating various craters and aspects of meteor study, mining equipment, and aerial surveys. There are also letters by fellow college classmate Woodrow Wilson, whose correspondence indicates that Barringer was not only a friend but also a personal adviser on mining and geological matters. In addition, the correspondence includes letters by Theodore Roosevelt, Owen Wister, General Leonard Wood, and Elihu Thomson.

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.

This series consists of printed maps, brochures, journals, and books.

Consists of novels, short stories, poetry and articles written by James Gould Cozzens as well as works by others.
