Fonds consists of correspondence and literary manuscripts, documenting all aspects of MacMillan’s career. Biographical background is provided by his own notes on his life and family history. From his student years come certificates and testimonials in support of his application for a Rhodes Scholarship (1904-1909). His war experience is recorded in letters from the front preserved by his family, and by a personal diary for 1917. There are also approximately twenty photographs of Macmillan and his family taken between about 1905 and 1940.

Macmillan's correspondence includes files of letters to his wife (1917-1936) on his war service and political affairs; personal and social letters (1923-1929); political correspondence, including several letters from McKenzie King (1926-1946); letters concerning McGill, including a number from Sir Arthur Currie and from Stephen Leacock (1920-1947); post-retirement correspondence on McGill and public affairs; and correspondence concerning his publications (1920-1960). There are also files of invitations to events at McGill and elsewhere.

The manuscripts fall into two categories: political speeches and literary manuscripts. Besides notes and texts for his own speeches, there are also texts of, and newspaper clippings about speeches written by Macmillan for Sir Arthur Currie and others (1920-1950). Drafts and typescripts of his literary works are supplemented by notes, clippings and correspondence.

Fonds consists of original files and printed materials falling into two themes. The larger of the two concerns Pavlasek’s work on the Superior Council of Education (1967-1972). Correspondence, notes and minutes deal with the establishment of the Université du Québec, the organization of a Council of universities, and legislation regarding capital funding of universities. The McGill Senate is the subject of the second group, comprising correspondence, minutes, reports and submissions from 1963 to 1971.

Fonds contains copies of two essays, “My Life as a Student and Teacher at McGill: 1934-1974 (1974)”, and “Innovation and Personal Strategies: A Study of Work in a New Outpatient Clinic”, co-authored with Anita Heller (1976).

The McGill Poster Collection documents posters and ephemera announcing campus activities, primarily in the 1970s with some 1980s and 1990s material present.

The fonds consists of a Strathcona Prize Plaque from 1939 and a scrapbook compiled by Dorothy Graham McCaig during her time at McGill, 1936-1937. Notably the scrapbook includes news clippings and memorabilia of the Student Peace Protests.

Fonds consists of papers (originals and printed materials) falling into three series: speeches; files relating to McGill committees before Ross was Chancellor; and personal and biographical materials.

Apart from formal speeches delivered as Chancellor at the opening of buildings and convocations, Ross's addresses and articles reveal his interest in professional development and research in accountancy and questions of national economic policy. These were written for, or delivered to McGill conferences, meetings of professional organizations of chartered accountants, financial analysts and business executives.

Files on McGill committees contain minutes of the Committee on Fraternities (1959-1962) and of the Committee on Chartered Accountants at McGill (1950-1951).

Ross's biographical files contain degrees and certificates (1927-1977), programmes and other memorabilia from Oxford (ca 1930-1932), news clippings about Ross (ca 1963-1968) and a few items of personal correspondence (1964-1974). His trip to Russia is documented by correspondence, notes and printed materials (1967-1969), and he wrote formal accounts of his journeys to South America and the Far East. A personal financial account book covers the years 1964-1969. These materials are supplemented by obituary clippings and letters about Ross written to his wife after his death (1974-1979).
