The Ross family fonds consists primarily of records related to the student achievements of the Ross children and includes student notebooks, news clippings, convocation programmes, certificates, and memorabilia of the Red and White Revue such as songs, photographs and original songs. Edward Russell Paterson’s student notebooks in geology, petrography and English literature are included.

In addition, there are two diaries of William Stieven Paterson’s from his travels through Civil War battlefields in the southern USA and a trip to Cuba; 8 photograph albums depicting the Paterson side of the family; 3 scrapbooks of magazine stories for children, poems and household hints; and correspondence between Dorothy Jean Ross and the McGill University Archives.

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 Lyman-Scrimger Family Fonds consists of the papers of the Lyman, Scrimger and Johnston Families. Reverend John Scrimger's daughter married Walter Ernest Lyman and their daughter, Elizabeth, in turn married Wyatt Galt Johnston. Elizabeth's sister is Mary Minta Turnor.

The Lyman-Scrimger papers largely consist of approximately 42 cm of photographs. Two albums contain family portraits, while two others assembled by Albert Clarence Lyman (B.A., 1878) and Walter E. Lyman (B.A., 1881) also include pictures of McGill classmates. The large collection of unbound photographs contain a number of views of Western Canada taken ca. 1900, Montreal scenes, and travel snapshots taken in Europe (ca. 1905-1910). Two scrapbooks compiled by the Reverend John Scrimger contain newsclippings, poems, cards, letters, photographs, and memorabilia of a family or sentimental nature. The reminder of the papers consists of newsclippings, programmes and so forth related to members of the family as well as a few scattered items of correspondence, probably collected by Mrs. Walter Lyman.

The Johnston Family papers comprise Wyatt Galt Johnston’s laundry lists and grocery accounts, ca. 1899; a letter to Elizabeth Johnston from her mother in Lennoxville, 1906; H. Wyatt Johnston’s school reports, 1907-1911; and letters of sympathy and memorial cards sent to H. Wyatt Johnston on the death of his mother Elizabeth Johnston, 1943 and his aunt Mary Tunor, 1945.

Mary Minta Turnor’s papers consists of correspondence, largely with members of her family in the Eastern Townships on domestic news. A few photographs of houses and pets, as well as some recipes, are also included.

The collection consists of ephemera, artifacts, and publications related chiefly to the Expo 67 World Fair in Montreal and some documents relating to its continuation, Man and His World (Terre des Hommes), an exhibition that was the successor to Expo 67. Many of the records and artifacts were produced by participant countries and sponsors or by the Canadian Corporation for the 1967 World Exhibition. Ephemera includes postcards, visitor passports, and ticket stubs, while other textual documents include guidebooks, magazines, catalogues, books, clippings, information manuals, and some unpublished planning documents. Artifacts include license plates, vinyl records, letter opener, bottle caps, shopping bags, and pins. The collection features pamphlets and brochures for numerous pavilions, events, services, and countries featured, as well as many maps for the Expo 67 grounds and documents related to subsequent seasons of Man and His World.
