The Arthur M. Adams Manuscript Collection consists of approximately 5 linear feet of documents pertaining to Adam’s work as a pastor and a professor. Inclusive dates are from 1942 to 1979, with the majority of the content falling between 1950 and 1970. The collection has been divided into three series, grouped by subject matter. These series are 1-Sermons, 2-Teaching Materials, and 3-Bible Class Talks.

The collection primarily consists of sermons delivered between 1848 and 1894.

The collection consists of papers and other materials covering Gillespie's life as a student, pastor, professor, and administrator. Much of the material includes correspondence and other communications between Gillespie and others. The bulk of the collection spans his presidency at Princeton Theological Seminary.
