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.

The D'Aigle papers fall into three series: diaries, correspondence and a scrapbook of photographs and memorabilia. The diaries (1912-1914, 1927, 1935-1952) are largely devoted to a day-by-day account of prospecting journeys. Correspondence with members of his family, partners, prospective financial backers and government mining bureaus covers the years 1900-1959. The scrapbook contains personal mementos, newsclippings about D'Aigle, photographs of his journeys, lists of supplies for prospecting trips, and maps, some drawn by D'Aigle himself.

The records of the Montreal-Ottawa Conference of the United Church are arranged in the following series:

1. Denominational records prior to Union, 1824-1925
   Records of each of the three parent denominations follow the same general pattern. There are minutes, usually printed, of the national executive body, and original minutes of the local unit corresponding to the geographical boundaries of the present Conference. Papers of associations at this level generally include the files of Sabbath School associations, ministerial associations, missionary societies, and theological colleges. A number of interdenominational clergy and mission groups are also represented; while a special series of correspondence, minutes, and conference reports covers the debates concerning union, 1906-1925. The Methodist materials begin in 1824, and the Presbyterian in 1841, and the Congregational in 1842.

2. Conference records, 1925-
   Minutes of the Conference, and of the Conference-based Women's Missionary Society, Women's Union and United Church Women, are extant from the time of Union. The Montreal Presbytery maintains a record of proceedings, and supports a number of groups and associations (Minister's Wives Association, young peoples' groups, camps, missionary societies, United Church Women) whose work is documented by minutes, financial records and, occasionally, correspondence files. Also included are records of the Joint Theological Colleges of McGill University and of the United Theological College, 1912-1948.

3. Local Churches, 1832-
   Many local churches retain their historical records, including civil registers. The Archives' holdings include records of approximately 75 individual congregations in the Montréal and Québec-Sherbrooke Presbyteries, consisting of minutes of governing bodies, communion rolls, minutes of organizations, accounts, annual reports, and occasionally photographs and architectural drawings. The most substantial and significant records are those of the Erskine and American (from 1832), including records of Canada Education and Home Missionary Society, 1833-1848, St James (from 1820), Zion Congregational (from 1832), and Odelltown (from 1829) congregations.

4. Missionary Work in French Canada, 1848-1861, 1876-1969
   The importance to the United Church and its parent denominations of mission work in French Canada is documented by minutes of the French Canadian Missionary Society (1848-1861), and papers, including sermons, notebooks and correspondence of the French Evangelical Church of Canada (1876-1969).

5. Papers of individuals, 1822-1925
   Papers of individuals include the correspondence, essays and sermons, 1870-1917, of Calvin E. Amaron; the Bieler Family; J. Armitage Ewing (largely concerning the controversies surrounding Union in 1925); William Mair, sermons, 1827-1855; Richard Robinson, diaries, personal records, sermon outlines, 1857-1912; Henry Wilkes, 1822-1878, and others.

Booth's autobiographical notes, ca 1949, apparently prepared for a Congregational Yearbook, are supplemented by sixteen photographs, printed notices of Booth's performances as an elocutionist, and diplomas.

Wallis' papers are grouped into three series: general scrapbooks, military scrapbooks, and military diaries. General scrapbooks, covering the years 1908-1977, contain letters, photographs, and printed materials relative to Wallis' career. Some volumes include his diary for the period, and all are heavily annotated. They cover all aspects of his career from high school to post-retirement, with special emphasis on his military career and social life. Military scrapbooks contain the same variety of materials for the period 1911-1969, but are devoted exclusively to Wallis' activities during the two World Wars, and his roles in the Black Watch and as an Honorary A.D.C. Military journals give brief reports of his daily activities form 1941 to 1945.

Lewis' papers consist of a few scattered items apparently assembled as part of his research for Royal Victoria Hospital 1887-1949, Montreal, McGill University Press, 1969. Newspaper clippings, 1932-1964, deal with Montréal and R.V.H. history. Lewis' correspondence, 1965-1971, with the Dominion Archivist, the McGill Archives, Dr. John Cleland, Mrs. Ellen Scrimger and others discusses various historical materials connected with the hospital. Also includes notes on material in the R.V.H. archives, some hospital newsletters and photographs, and a few reprints and addresses.

Campbell's papers contain some students materials, a small amount of correspondence, and commemorative materials associated with his retirement in 1950 and his 75th birthday in 1961. Student materials consist of mimeographed lecture notes for a course by Dr. J.C. Meakins, with Campbell's handwritten notes. The subjects covered are heart and lung diseases and the nervous system. Correspondence consists of a letter from Lady Drummond offering the services of the Canadian Red Cross Society to Campbell, 1917. A volume of photographs and biographies of doctors and nurses connected with the Department of Obstetrics and Gynaecology at the Montreal General Hospital, 1883-1950. was assembled by Campbell himself. Also included is 4 cm of correspondence and questionnaires, largely from former interns and residents who had served under Campbell's regime. An album of letters from former colleagues and friends commemorates Campbell's 75th birthday, 1961.

Most of this collection consists of the selected incoming personal correspondence of Caroline H. Pelton, 1846-1873, and some correspondence of members of her family, 1842-1905. Also included are two diplomas awarded to Caroline Pelton from the McGill Normal School, 1860 and 1861 and family photographs. There are also selected financial records of St. George's Church, Montréal, 1882-1885.

Selected papers of the Hart Family include a diary kept by Bernard Samuel Judah (an in-law of the Harts) during a voyage to the United States to visit his son Samuel, 1827-1828; a Jewish calendar belonging to Alan Judah Hart with notices of family births and deaths, 1903-1930, and few diary entries, 1917-1919; a few items of correspondence of Alan Hart and his family relating to family history, 1923-1972; some notes on family history, and 25 portraits (photographs, silhouettes) of family members from 1823 to ca 1960.

Programmes (particularly of R.V.C. plays and sports events), clippings, and photographs are also included. There are also course notes for C.W. Colby's Renaissance history and William Caldwell's history of modern philosophy.
