Fonds consists of records (originals, printed materials, photographs and motion pictures) that are almost entirely of a professional and research nature, covering Barnes’ general scientific and university work during World War I, a number of special research problems, and his involvement in scientific and social organizations.

His general scientific and university files (1914-1915) contain correspondence, including copies of some of Barnes' outgoing letters on departmental adminstration, Barnes' lectures, publications, scientific apparatus, research problems and the exchange of information. Correspondents include colleagues in other institutions (including Ernest Rutherford), learned societies, and private industry. This series also contains a file on purchases for the University Library, and inventories of Barnes' library.

Far more extensive are the materials on special research problems. These comprise notes, essays and correspondence on the detection of submarines (1915-1917) and on the development of anti-freezing devices for fire extinguisher and sprinkler systems (1917). A report by Barnes on the effect of ice conditions on St. Lawrence navigaton is supplemented by printed background materials and copies, or extracts from other reports. Barnes' work on icebergs is documented by five binders of clippings, photographs, maps and diary notes on research expeditions to Newfoundland (1924-1929). Practical experiments in ice clearance are illustrated by bound notebooks of clippings and photographs, as well as a number of loose photographs showing ice and flooding damage, use of thermite and calcium chloride, apparatus and ice-crushers (ca 1921- 1929). Finally, two reels of 35 mm motion picture film (ca 1930) show Barnes experimenting with a new mercury microthermometer.

Barnes' work as Hon. Secretary of the Canadian Committee of the British Science Guild is documented by correspondence from 1907 to 1919, largely concerning the recruitment of members and officers, but also touching on a survey of science teaching in schools and the Panama-Pacific Exposition of 1917. Less extensive files cover Barnes' involvement in the International Council for the Exploration of the Sea (1912-1914), the Rotary Club (1917) and the McGill Graduates' Society (1919)

Fonds documents Dr. H.E. MacDermot's medical-historical activities. The fonds contains newspaper clippings, manuscript notes, photographs, lectures notes, and a draft of The MGH, the Years of Change.

Fonds documents J.B. Johnston's professional activities from 1839 to 1859. It also includes his medical thesis De delirio tremente, Edinburgh, 1833. The fonds contains a logbook with notes, summaries of readings, reports of unusual medical cases and obstetrical list, and his medical thesis.

Snell's research files for his history of Macdonald College contain drafts of the book, and files of notes, extracts and clippings collected as background material. Included are two volumes of an attendance register from an unidentified Québec public school, 1857-1869.

Stansfield's student notebooks comprise three volumes of the geology lectures of Dr. Marr (1904). Research notes include laboratory records and a draft article on dolomite, and scattered notes on palaeontology and stratigraphy. His work as a teacher is documented by lecture notes on economic geography for a course given to McGill commerce students (1911).

Fonds documents Dr. Lella's research activities while at McGill.

The collection consists of informational files on Juda Hirsch Quastel, collected by T. L. Sourkes and F. C. MacIntosh for a biography of J. H. Quastel for "Memoirs of the Royal Society of London", vol. 36, 1990. The files include material from the Royal Society itself, letters from many people about Quastel, laudatory articles about him along with obituaries about his death, some notes by Hank in his handwriting, and other items.

The fonds represents over forty years of Julian Armstrong's career as a food writer and journalist. The fonds contains primarily textual records created and accumulated by Armstrong during her research into the culinary history and traditions of Quebec while a food editor with the Montreal Gazette. Series 1 consists of food research files arranged by Armstrong according to geographic location or subject. Generally, the files are arranged by Quebec town or region, but some are devoted to food research topics related particularly to Quebec, such as "tourtières". The second subseries is arranged by specific foodstuffs, such as "Maple Syrup Pie" or "Bread," or food-related topics such as chefs and restaurants, or nutritional or diet topics. Series 2 contains notebooks of Armstrong's notes taken during travels primarily in Quebec's regions with observations, interview notes, tasting notes, and information such as food prices. The notebooks begin in 1986, dating from when she began her travels in Quebec for her food reporting. Series 3 contains records related to Armstrong's publications and speaking engagements. Series 4 consists of documents created through Armstrong's participation in culinary associations such as Cuisine Canada and in various cooking contests. Series 5 contains notebooks kept by Armstrong between 1969 and 1995 tracking food prices at particular regional grocery stores, organized by food product.

The collection consists of correspondence, research files, manuscripts, journals, and ephemera created and accumulated by writer and scholar Leon Edel, who was notably the editor and biographer of Henry James as well as Edmund Wilson.

Fonds consists of original documents and printed materials concerning King’s research, but there is also some general correspondence, student materials, and personal papers.

Research materials comprise manuscripts, addresses, and research notes. The manuscripts and addresses (1901-1933) contain essays on fog-signals and the transmission of sound, radiation, the physics of viscous fluids, the hot-wire anemometer, astronomy, and theoretical problems. The research notes (1904-1935) comprise approximately 50 files. Eight of these concern fog-signal research (1915 1926) and include some correspondence. Other topics include radiation, physics of gases and liquids, acoustics, astronomy, electromagnetism and mathematical problems.

General correspondence covering the years 1908-1936 contains letters from his fellow physicists, including Rutherford, A.N. Shaw, E.S. Bieler and H.T. Barnes, on research and personal matters. There are also letters of introduction (1905), correspondence regarding his appointment at McGill, letters to the editor of Nature (1926), the National Research Council (1933-1934), and the Central Computing Bureau (1918). As well, files concerning ice research (1920), tests at Prescott, including his diary of the expedition (1920), and the St. Lawrence waterway (1931-1932) can be found here.

King's private papers comprise a diary for 1902, reading notes and reviews of Maria Chapdelaine (1919-1921), his pension papers, and an inventory of periodicals in his library. There are also two formal photographs and a number of snapshots of school groups, Cambridge scenes, and laboratory equipment.
