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.

Collection consists of one bound manuscript notebook softbound in a piece of brown leather. The notebook dates chiefly from 1841 and was produced in St. Armand by Philip Luke. The notebook contains a title page that has been lettered, illustrated, and coloured by hand: A Latin Translation / by Philip Luke. St. Armand. 1841. Commenced April 4th. The text within this first portion of the notebook is Aesop's Fables in English and Latin on facing pages. The first part of the manuscript ends with "13. Horse and Ass" (Latin is incomplete) and "32. Widow and Servants" (Latin text missing). The following leaf contains two medical recipes: "A cure for a felon or whitlow," refering to an abscess or infection of the fingertip and consisting of a paste made from egg yolk, honey, turpentine spirits, camphor, and flour, and "A reciet for the inflammatory rheumatism," involving a wine-based tonic containing three types of bark, horseradish, brandy, and tar water. Following another blank leaf, a partial letter is found dated 1839. Philip Luke's text begins again in the latter part of the manuscript with a second coloured title page: "Dialogues and Declamations." There is also one loose note laid in dated 1809, a receipt for 100$.

Fonds consists of the personal and professional papers of Louis and Irene Kon including extensive correspondence between the Kon family. Included are materials relating to the founding of the Norman Bethune Foundation and Bethune memorials; the making of Ted Allan's movie, "Making of a Hero", including the conflict with Syd Gordon regarding creative differences; a manuscript draft and notes on Larry Stephenson's manuscript 'Two Petrals.'

The collection consists of documents amassed by Roderick Mackenzie. Among the Masson manuscripts there are other series of letters; as well as journals kept by North-Westers and various business documents. Some of this material exists as originals; others are contemporary copies - the George Keith letters for example are contemporary copies on paper watermarked 1827. The collection also includes some duplicate texts - contemporary copies or later nineteenth-century copies that in some cases represent edited versions of the texts. Samuel Wilcocke's account of the death of Benjamin Frobisher exists in a draft original (or contemporary copy) and in a late nineteenth-century clean copy. Of course Benjamin Frobisher did not die in the dramatic circumstances as recorded by Wilcocke, but peacefully in Quebec City in 1821.
