The fonds documents Sharon Thesen’s personal and professional life as a poet, editor, and professor from 1961 to 1989. All records in the fonds were collected by Thesen herself, and are primarily composed of correspondence, journals, and creative work. Most of the creative work is composed of drafts and edited versions of Thesen’s own poetry, essays, and articles, but also includes work sent to her for review. While most of the records are textual, there are a small number of pictures and postcards that were sent to and taken by Thesen, and are mostly of a personal nature. Notably, a large section of the fonds is made up of letters that include correspondence between other published and acclaimed authors such as Michael Ondaatje, Christopher Dewdney, Lola Lemire Tostevin, Ken Norris, Judith Fitzgerald, Phyllis Webb, Gerald Burns, and others. Lastly, the fonds also includes Thesen’s journals from the mid-60s to the mid-80s which contain her daily activities, her personal thoughts, as well as some of her creative work.
The fonds is arranged into three different series, Chronological Files, Journals, and Personal & Professional Records, as per the internal organization of the records.

The William Weintraub fonds documents Weintraub's career in documentary film and literature covering the period between approximately 1950 to 2000. The fonds falls into four series: (1) literary correspondence, (2) literary activities, (3) documentary filmmaking, and (4) biographical materials, personal correspondence, and career ephemera, documenting Weintraub's early life as well as theatre programs, pamphlets, and other collected material. Weintraub's career as a documentary film maker both as a freelance and with the NFB (1965-1986) with some 150 films to his credit is well documented including his work in Africa. The material includes scripts, research notes and correspondence. In some cases copies of the films are included. Material related to the NFB also includes newsletters, office files, and correspondence. The material documenting Weintraub's literary career includes drafts, proofs, correspondence and reviews for his two novels Why Rock the Boat? (1961) and The Underdogs (1979). In addition, the former was made into a film and extensive files relate to this. The latter novel was adapted for the stage and drafts, publicity and material relating to the controversy it aroused are included. Weintraub's book on Montreal in 1940s and 1950s City Unique (1996) is documented with extensive research files, drafts, reviews and correspondence. The literary correspondence with Mavis Gallant (127 letters), Brian Moore (603 letters) and Mordecai Richler (210 letters) constitutes a major source for the study of three prominent Canadian writers in the last half of the twentieth century. In addition, there are copies of 280 letters from Weintraub to Moore and 123 copies of letters from Weintraub to Richler. While the Gallant correspondence dates primarily from the 1980s with only 8 letters from 1950-1951, the Moore and Richler correspondence is continuous from the 1950s. This latter correspondence reveals the close involvement of Weintraub in the development of the work of both Moore and Richler.
