Oliver's papers deal almost entirely with his work for the Royal Commission on Biculturalism and Bilingualism. Correspondence, minutes, reports and press releases document the Commission's meetings, organization, personnel, and finances. There are also briefs, reports of study groups, drafts of the final report, and files on individuals. Records of his Vice-principalship at McGill can be found in Record Group 3.

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.

Madame Fischer's papers are evenly divided between records of her own career as a performer and material on the Sarah Fischer Concerts. Her performing career is documented by newsclippings, tributes and programmes, reports from the Royal College of Music, and publicity photographs in opera costume. Most of the approximately 50 items of correspondence date from the last five years of her life and concern the disposal of her papers. Taped interviews, in which she discusses her career, include recordings from 1918 and 1925. Material connected with the Sarah Fischer Concerts comprises 143 programmes (1941-1975), press notices, announcements, and a report for 1973-1974. Photographs from this period show Fischer with government and musical celebrities.
