Series 4 contains a variety of types of papers, and incorporates both original documents and photocopies and photostats of material located elsewhere. Materials are arranged according to chronological order rather than by type or theme.

The Origins series chronicles the origins of Princeton University (until 1896 the College of New Jersey); its predecessor institution, the Log College; and its original locations in Newark and Elizabeth. Included is information related to early gifts and purchases; and various historical influences.

The courses and projects series consists of records documenting the courses Clark taught on the topic of Princeton architecture as well as his participation in the Evolution of a Campus project, a dissertation he advised, and a book he proposed to write. The records of Clark's classes include student papers, syllabi, classroom handouts, and a small amount of correspondence. The Evolution of a Campus records consist primarily of financial records as well as preliminary tests of the three-dimensional modeling software and some correspondence.

The demonstrations series documents the protests, strikes, and riots coordinated by or chiefly involving members of the Princeton University community (sometimes only students, but often including faculty and staff as well). Many early demonstrations, such as the 1800 riot, were the result of student unhappiness over the rules of an intransigent administration, such as the "unreasonable" mandatory daily 6am chapel services, which were extremely cold in the winter. Not all protests, however, involved significant internal dissention. In 1970, students, faculty, and administration largely came together to declare a strike against President Richard Nixon's expansion of the Vietnam War into Cambodia.

Includes Committee Records.

The Fundraising series documents University fundraising efforts and the Development Office. Much of the series consists of materials that accompanied Princeton's many capital campaigns, although the series also contains significant information on University funds, major donors, and annual giving.
