The fonds consists of Dr. Campbell's partially edited and unfinished autobiography, which he began writing in the 1960s and continued until the time of his death in 1970.

Much of the material concerns the Seigneurie de Vaudreuil. Other material include correspondence (1809-1821) with Joseph Bouchette; extracts from the registers (1667, 1732) of the Conseil Souverain and the Conseil Superieur; and documents concerning Newton Township, the Seigneurie des Mille-Iles.

Eve, 1930, and three binders of biographical material photocopied from books and journals, with photographs, sketches and bibliographies, prepared by his son A.D. Macallum, ca 1969-1972.

The majority of this collection is correspondence between Annie Holiday Pelletier and her parents Elise and William Holiday. The collection also includes correspondence with and between other family members, photographs, genealogical and biographical information, and miscellaneous material about the Rondeau, Holiday, and Pelletier families. Included is an early written exchange, circa 1864, between Elise Rondeau and a local parish priest who disagree on religious freedom and the interpretation of a biblical passage. The correspondence between Annie and her parents, including the period in which she is a student at McGill, is written in French (from and to her mother) and English (from and to her father). This correspondence provides a vital resource on early student life and the day-to-day concerns of a young woman living away from home in late 19th Montreal. The correspondence is rich in its detail and frankness on matters of family life, conflict, and religious and educational issues.
