Collection consists of 38 letters written primarily by John Wood Senior to family members in England. Many of these were written to a sister or sister-in-law and a few are addressed to his brother, Will Wood, a watchmaker and jeweller in London, including two in which Wood includes a list of trade supplies to order. Four letters are from John Wood's son, Peter Wentworth Wood. One letter is by John's wife, Anna. Contents include topics such as the country's economy, Canadian-British politics, the Woods' watchmaking and jewellery business, crops, slavery, and the American Civil War, as well as local Montreal news on subjects such as fires, the Victoria Bridge, a cholera outbreak, the 1856 Railroad Celebration, and a visit by the Prince of Wales. Letters also include family news, particularly of John Wood's children Peter, John, and Charles, seafaring disasters, gold mines, improvements in shipping in the St. Lawrence seaway and the Atlantic Ocean, the expansion of railroads, and the Atlantic Telegraph. Letters date between 25 November 1839 and 13 December 1867. One is a crossed letter.

Fonds consists of six autograph signed letters written at Montreal by Ann Adams, dated between 24 March 1834 to 26 December 1937, to her son Edward H. in Providence, Rhode Island, and Philadelphia. Letters contain local news (churches and organs built, the railroad to St. Johns, fires, printing and publishing, cholera, etc.), observations on the worsening tensions between Papineau and the "Canadiens" and the "Loyalists," and accounts of preaching by an Indigenous convert to Christianity.

The fonds consists of the records of the Zoological Society of Montreal for the entirety of its existence, from 1964-2016. These records were generated in the pursuit of the Zoological Society’s goal to enhance public awareness of wildlife conservation issues through speakers, film screenings, field trips, special events, and large projects. The records also reflect the Society's charity to zoological, ecological and conservation causes. The administration of the Society, its interactions with its members, and its projects and events are documented through minutes, correspondence, communications, published articles, financial documents, reports, and proposals. The Society’s interests and activities are also reflected through books, objects from their offices, audio and video materials, and 5243 photographs, most of which are stored in photo albums. The fonds also contains the records of the Zoological Society of Canada, which were created to administer the Canadian Society similarly to the Montreal Society, with the goal of expanding the organization’s reach nationally.

The fonds is comprised of the following series: 1) Activities (1965-2013); 2) Administration (1964-2016); 3) Artifacts (1980-2004); 4) Books (1967-1991); and 5) Newsletters (1967-2016).

Fonds consists of manuscript copy of Milledonne's "Giornale del Concilio Tridentino".

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.

This diary written at Rome, 1848-1855, is in English, French and Italian.

Fonds consists primarily of correspondence between Hertel de Rouville and members of the Canadian government, including Chief Secretary of Lower Canada Sir Thomas William Clinton Murdoch (1809-1891) and Governors General Lord Gosford and Charles Bagot, regarding financial losses he incurred during the rebellions of 1837, 1838, and 1839, and half-pay claims dating from his time as captain of the Canadian Voltigeurs during the War of 1812. Also included are five envelopes with wax seals intact.

Fonds consists of a one document, a manuscript of reminiscences of Charles James, born in Montreal in 1835. The document is internally dated in April 1915. James describes his childhood as the son of a carriage and sleigh builder born in England who conducted much business for the British military stationed in Montreal. The family resided on Craig Street. Reminiscences include descriptions of Montreal, the building of the locks on the Lachine canal, a trip up the Ottawa River to Bytown (Ottawa) and then to Kingston, where the family resided for a time. James joined his father in the trade of carriage trimming as a young man before becoming a Baptist minister in Stratford, Canada, and later Wellesley.
