This series is made up solely of materials kept in the Office of the President. While the items date from 1948-1977, the majority of the materials date from after the construction of the uptown campus, with many pieces dating from the presidency of Louis Benezet. The subject of the materials vary greatly, and cover important events in the University history such as the construction and relocation to the uptown campus and campus unrest in 1970. The president covered in this series are Nelson, Collins, Kuusisto, Benezet, and Fields. Many boxes contain papers related to multiple presidents, connected by a common subject at times. Others are dedicated to a single president and subject. Specific materials in the series include blueprints of new construction, annual reports, master plans for the University, and reports from individual departments.
