The commonplace book of the Morris family includes copied extracts from the journals of Margaret Morris, which include a description of Yellow Fever in Philadelphia in 1793, as well as copied poems, letters written by Mary Morris and Richard Hill Morris, and a clipped illustration depicting early settlers.

This collection is comprised of the papers of Isaac Proctor. The majority of the collection is composed of the personal correspondence of Proctor from the end of the 18th century, but also includes a single, small diary, and a single folder of his financial records.
