The fonds contains the majority of the drawings and papers of Montreal architect and landscape architect John Schreiber, who was a professor in the School of Architecture at McGill from 1953 to 1987. These documents constitute a rich treasure of original design work, expressed in draughtsmanship of great virtuosity. John Schreiber’s work is an example of the contribution to Canadian architecture and landscape architecture of a generation of Europeans who, leaving that war-shattered continent in the late forties and fifties, found an appreciative and fertile ground for their talents and ambitions in Canada. The two hundred and thirty four projects represented in the Schreiber fonds span half a century of work and are documented in more than four thousand plans and drawings, hundreds of photographs and close to six linear metres of textual files.

The fonds comprises nine series (including seven main categories of information) of records on the life and career of Frederick B. Taylor. It is the largest collection to date on Frederick B. Taylor. Biographical Information includes an excerpt from an unpublished autobiographical manuscript, Essays includes works such as "Reflections on painting Stephen Leacock", Photographs includes both professional and social snapshots. Two main facets of the Archive which hold particular interest are Works and Correspondence. Works includes over 1550 reproductions of Taylor's work. This selection is a cross-section of Taylor's artistic mediums and includes painting (landscape, industrial, portrait, still-life), etching, drawing, sculpture as well as six original prints and seven original canvases located at McGill University. Correspondence comprises some 2000 letters, documents or memorandums, spans from the early 1920s up until Taylor's death in 1987 and is divided into professional and personal series. The professional series focuses primarily on the relationships Taylor held with various private galleries and exhibitors of his work including the Klinkhoff, Kastel and Dominion Galleries in Montreal, the Roberts Gallery in Toronto as well as numerous Canadian public galleries and museums which remain repositories of Taylor's work, among them the Canadian War Museum in Ottawa. The personal section demonstrates Taylor's substantial and often life-long relationships with his family and friends, among them, artists André Bieler, Alan Harrison and Carl Allen Smart as well as Paul Wakefield and Colin Wyatt.

The fonds contains correspondence related to the Osler Library and its holdings with people such as Maude Abbott, Edward Archibald, William B. Bean, Edward Horton Bensley, Archibald Malloch, Casey Wood, as well as John Farquhar Fulton, Keeper of the Medical History Collections at Yale University's library; the fonds also contains a typescript of talks by W.W. Francis (titled "Showman's Patter") about books and other items held in the Osler Library.
