The administrative records of the MCSA contain annual reports, 1921-1968; minutes of annual meetings, 1956-1971; minutes and correspondence of the Board of Governors and its Executive Committee, 1953-1972; files on budgets and staffing, 1962-1973; and documents on the merger with the Conseil de Développement Social. The operations of standing committees (Committee on Committees, Admissions and Standards, Nominating, etc) are documented by broken series of minutes from 1937 to 1971. Far more extensive are the papers of special committees researching social problems such as school leaving, 1934; single parents, 1949; housing and urban renewal, 1967-1971; dental services for children, 1950-1961; and low-cost medication, 1970-1971. These files include case work studies, correspondence, minutes and reports. The question of day care is particularly well covered, both through committee materials and through the files of Barbara Heppner, MCSA Day Care Coordinator, 1969-70. Correspondence files contain letters and reports from member agencies, university schools of social work, co-ordinating bodies such as the Canadian Welfare Council and the Conseil de Bien-Etre du Québec, various citizen's groups, and government bodies. A large percentage of this material consists of information files, containing reports of, and studies by, American and Canadian social agencies, conference and workshop proceedings, and materials on social legislation.

The fonds consists of documents, photographs, films, and objects relevant to the professional and personal history of Samuel Joseph Noumoff. The scope predominantly covers the period from 1970-2006, and includes Professor Noumoff’s published articles and unpublished drafts, including some translated editions. His personal papers include professional and personal correspondence, especially letters to and from his wife Francesca and the contacts he made during his travels, materials related to his family history, photographs and ephemera of his travels in South East Asia.

Traquair's papers largely concern his work as a lecturer. School of Architecture lectures in architectural history cover the classical, mediaeval and modern periods (ca 1935-1936), while those on architectural ornament are largely devoted to lettering. Miscellaneous lectures, about 30 in number, were delivered between about 1924 and 1937 to various audiences, such as school children, extension students and members of art and architectural associations. They deal with architectural history, architectural principles both aesthetic and social, and other art forms (painting, carpets, heraldry etc.)

Material relating to Traquair's publications includes drafts of about 15 articles on many of the same topics as the lectures described above, and stemming from the same period. A special series of notes and manuscripts, together with some correspondence, illustrates Traquair's research on Québec arts.

Most of this material concerns the last illness and death of Robert Harvey Warden, and comprises letters of sympathy to himself and his wife, and following his death, condolences to his wife and children. The letters are from personal friends as well as from Presbyterian bodies. Printed obituaries are also included. Letters of condolence to Mrs Warden on the death of her daughter Lila Dunton are likewise accompanied by newspaper obituaries, 1908.

The major record of the McGill Chapter's early years is a register containing members' signatures, 1911-1969, and minutes from 1912 to 1932; a second minute book covers the period 1960-1969. Approximately two-thirds of the papers are secretary's files from 1961 to 1978 containing membership lists, correspondence concerning prospective members, circular letters announcing meetings, and correspondence with the headquarters of AOA. There are also receipts for initiation fees from 1954 to 1969.

Scrimger's papers mainly concern his war service. His brief diary of the Ypres campaign, 1915, is supplemented by signals and military messages on troop movements and medical matters; Scrimger sometimes used the signal forms for additional diary entries. There are also a handful of letters and cables of congratulation on his V.C., certificates of service, newsclippings, and printed souvenirs. The remainder of these papers consist of obituary notices and tributes. Some are pasted into Scrimger's notebook of Professor Bier's clinic, Berlin, 1910.

About half of Donald's papers consist of diaries giving brief daily records of his professional and sometimes personal activities from 1918 to 1981. The remaining files fall into two series. Essays and addresses, 1919-1962, largely on economic aspects of the chemical industry, were addressed to professional organizations and commercial bodies such as the Engineering Institute of Canada, the Canadian Chemical Association, the Canadian Chamber of Commerce, and the Industrial Development Board of Manitoba. More informal speeches include a radio talk on jobs in the chemical industry, 1938. Personal materials comprise some family, legal and investment records, 1940-1952, and undergraduate essay on medieval universities, 1910, correspondence related to an annuity fund set up by Donald for Jessie Henderson, secretary and librarian of McGill's Chemistry Department (1946-1961), and a file of press releases and congratulatory letters on Donald's receipt of the Chemical Industry Medal, 1952-1953.

The bulk of Gill's papers concern his consulting work for the mining industry and for government. Only two small files relate to his teaching career. Gill's work as mining consultant is documented by 124 maps, 48 designed by Gill himself, showing structural geology of various regions in eastern Canada, and mineral deposits of gold, iron, zinc and molybdenite, not only in Canada, but also in the Malartic gold fields in Peru (1929-1968). The papers also contain his report on iron ore in Labrador (1929) and two reports by W.F. James and J.E. Gill to the Newfoundland government, assessing prospects for gold in the Rainbow and Kayak Concessions, Labrador (1933), areas prospected by R.B. D'Aigle, see his papers, Section IX: Professions And Trades. IX). Three field notebooks record summer research expeditions (1935, 1947-1948). Three reports by Peter Eakins, a former student of Gill, describe the Malartic mine (1951, 1955-1956); there is also a report by Eakins on the Wasa Lake Goldfield (1950), and one by J.B. Gilliatt on the Wabana Iron Mines (1949). Gill also raised a file of correspondence and reports on Newfoundland mineral resources (ca 1955-1969). Finally, there are two boxes of petrographic slides, one with laboratory reports, a box of mineral samples collected for the Québec Ministry of Mines, and 4 photographs of mining concerns with which Gill was involved. His teaching activities are reflected by a file of plans, reports and memoranda on the organization of the Geology Department Map Library (1959-1969) and an outline with some draft chapters of a student's thesis (1969).

The Society's bank book,1913-1925 and receipt book, 1924-1925, are accompanied by a newspaper account of its annual outing in 1889, and a photocopy of the notice of a meeting, 1890.
