Fonds consists of six letters, with four manuscript letters from Rilke written between 1896 and 1922 and two discussing letters discussing these. The four letters from Rilke are addressed to various correspondents, including on 8 November 1896 to the author Gabriele Reuter regarding her book, 15 October 1904 to Anette Vedel, and 9 July 1907 to an unidentified correspondent. The fourth letter dates likely from August or September 1922 and is addressed to Elfriede Nicolaus. The two later letters which discuss the Rilke letters include one dated 13 December 1954 from Hedvig Wahlgren regarding the date of the 1922 letter to Nicolaus and one dated 29 November 1955 from Ruth Fritzsche (née Rilke) to McGill Librarian Richard Pennington.

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 main forms of these records are textual records, but also include graphic/photographic materials and mixed media. The records are arranged chronologically and intellectually within the series.

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.

Three letters from Seaton relating to the Rebellion of 1837, including a letter to General Fitzroy Sommerset about the capture of St-Eustache.

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 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.

This series consists of research, writing, and correspondence files relating to Casey Wood's major and minor publications and unpublished works, as well as, others assisting in Wood's publications, research, or writing about Wood. The majority of the research and writing materials for Wood's published and unpublished works were created between 1920-1940, while other materials collected during Wood's life, those associated with his memoir and obituary, date from approximately 1850-1943.
Some prominent writings by Wood include “Introduction to the Literature of Vertebrate Zoology” (1921-1956), his unpublished memoir (ca. 1850-1939), “Fundus Oculi” (1911-1934), Wood family history (1920-1940), “Birds of Fiji” (1920-1928), “Through Forest and Jungle in Kashmir and North India” (1921-1934); Persian, Arabic and Hindustani manuscripts (1927-1934); and “The Art of Falconry” (1942).
The series consists of many volumes and files containing a number of record types including manuscripts, typescripts, proofs, publications, photographs, correspondence, clippings, printed material, postcards, journals, administrative and financial records, and artwork. Some of the volumes are scrapbooks containing many of these materials mounted within, while others include similar materials bound within. These volumes do not necessarily have a clear organization but are sometimes arranged chronologically or by correspondent.

There are 2230 incoming and outgoing pieces of correspondence including letters, postcards, notes, telegrams, and cards. Subseries 1) Introduction to the Literature of Vertebrate Zoology includes 1313 pieces of correspondence, the largest number of correspondence within the collection.
