The fonds consists of textual records (including correspondence, reports, minutes and course materials), published materials, and photographs documenting the life and career of Alden Barss. The records relate to the teaching of horticulture; the development of the Department of Horticulture, the Faculty of Agriculture, and the University; Barss' involvement with the Anglican Theological College and the Anglican Church; his professional career; and his personal life. Some records were collected and arranged by Barss in the course of writing a history of the Department of Horticulture.
