His files include correspondence with graduates, a card file of graduates, obituaries of classmates, menus and circulars (1920-1967). Jamieson's student materials comprise projects for a graduate course in strength of materials (1919), and his research activity is documented by correspondence, graphs, and a draft article on welding (1934-1936). Teaching materials include notes and problems for a mechanics course (1946-1952) and problems on indeterminate structures (1952).

This fonds consists of Bell's personal and research files from the period before his appointment as principal (1956-1969) and after his resignation (1979-1983). There is some material from his years as principal (1977), but it concerns Bell as a physicist or as a member of a learned society. The fonds shows Bell's involvement in professional associations, including correspondence, cyclical reviews, information on conferences, lectures, meetings, committees and projects.

Fonds consists primarily of Meek’s manuscripts of his keyboard and church music compositions, from approximately 1930-1975.

These professional papers of R.A.C. Henry cover every phase of his career from 1911 to 1960. A significant percentage relates to the St. Lawrence Seaway, and covers the period 1920-1960; these files contain information on estimated costs, power and navigation development, canal systems, engineering problems, Canada-U.S. relations, Québec and Ontario hydro, the implications of the project for the Montréal area, and historical aspects. The remaining files likewise contain correspondence, reports, memoranda and notes. Topics covered include railways in Canada and Mexico, 1913-1932; canals, particularly Lachine, Welland, and Sault Ste Marie, 1913-1915; the Québec hydro-electric industry, 1922-1946; Defence Communications Ltd., ca 1949-1954; air transportation, 1944-1957; and various reports on general economic questions or the affairs of specific companies for which Henry was consultant.

Tupper's papers are divided evenly between correspondence, 1928-1950, 1954 and financial papers, 1931-1948. The correspondence files were maintained by the Conservatory office, and thus contain Tupper's letters to the secretary, Miss Dawson, concerning the progress of his examination tours across Canada. Most of the letters are, however, of a social and personal nature, discussing Tupper's appointments, domestic finances, equipment (musical instruments, radios), musical arrangements for concerts and McGill events and the Montréal scene in general. Financial papers comprise invoices and receipts for domestic and private expenses.
