The Priscilla Ann Mabie Stewart papers date from 1932 to 2007 and measure 2.5 linear inches. The papers are arranged in two series: Biographical and University School. The bulk of the papers consist of general records from Stewart's years in high school, including school newspapers, yearbooks, memorabilia and reunion materials.

The Biographical series(1993) contains a copy of Stewart's Who's Who in American Education entry.

The University School series (1932-1958, 1972-1994) is divided into two subseries, Elementary school and Junior high and high school. The Elementary school file contains typewritten materials of Mabie's work, a school newspaper and programs from school functions. The Junior high and high school files contain typewritten school programs, newspapers, correspondence, clippings, and yearbooks.
