The fonds also notably includes Fitzgerald’s creative work, including notes, drafts, manuscripts, and copies of her published books of poetry. Other materials include correspondence between Fitzgerald and friends, publishers, and individuals and institutions that she covered in her research. In addition, the fonds includes some financial records and personal records relating to Fitzgerald’s day-to-day activities and significant events in her life.

The fonds consists chiefly of architectural drawings, photographs, reports, and other records relating to Erickson's architectural projects in the Middle East. The materials document Erickson's involvement with building projects in the Middle East. Erickson's concern for bold masses, indigenous forms and contextuality can be seen in designs for the Islamic University of Madinah in Saudi Arabia (1983) and the Abu Nuwas Conservation and Development Project in Baghdad, Iraq (1981). These designs are better understood as small-scale cities rather than buildings and reflect Erickson's humanist approach to the problems of Modern design. The majority of the architectural drawings in the fonds date from 1976 to 1986 and include 1,468 multimedia drawings. These include drawings for over a dozen Middle East competitions and projects such as designs for the Islamic University of Madinah, Saudi Arabia (1983), King Faisal Air Force Academy and Mosque in Al Kharj (1980) and the Etisalat Headquarters in Abu Dhabi, United Arab Emirates (1986). An additional seventeen drawings were created before 1950 and include nine drawings for an office building and eight drawings for an arts centre for Vancouver. These executed while a student at the McGill School of Architecture. The fonds also contains 102 photographs and 26 slides also dating between 1976 and 1986 as well as 4 three-dimensional scale models. These models are for the Islamic University of Madinah (1983), the Abu Nuwas Conservation and Development Project (1976), Sancst Science Halls (1981) and Etisalat Headquarters (1986). The fonds also contain competition submissions and project development documentation (1976-1987), bound in 43 volumes. Nine copies of three published books also included contain surveys of Erickson's work and career. The fonds also contains Erickson's correspondence and other papers.

Le fonds se compose principalement de dessins d'architecture, de photographies, de rapports et d'autres documents relatifs aux projets architecturaux d'Erickson au Moyen-Orient. Ces documents témoignent de l'implication d'Erickson dans des projets de construction au Moyen-Orient. L'intérêt d'Erickson pour les masses audacieuses, les formes indigènes et la contextualité se retrouve dans les projets de l'Université islamique de Médine en Arabie saoudite (1983) et du projet de conservation et de développement d'Abu Nuwas à Bagdad, en Irak (1981). Ces projets sont davantage considérés comme des villes à petite échelle que comme des bâtiments et reflètent l'approche humaniste d'Erickson face aux problèmes du design moderne. La majorité des dessins d'architecture du fonds datent de 1976 à 1986 et comprennent 1 468 dessins multimédias. Ils comprennent des dessins pour plus d'une douzaine de concours et de projets au Moyen-Orient, tels que le plan de l'Université islamique de Médine, en Arabie saoudite (1983), l'Académie de l'armée de l'air du roi Fayçal et la mosquée d'Al Kharj (1980) ainsi que les quartiers généraux d'Etisalat à Abou Dhabi, aux Émirats arabes unis (1986). Dix-sept autres dessins ont été réalisés avant 1950, dont neuf dessins pour un immeuble de bureaux et huit dessins pour un centre d'art à Vancouver. Ces dessins ont été exécutés alors qu'il était étudiant à l'école d'architecture de McGill. Le fonds contient également 102 photographies et 26 diapositives datant également de 1976 à 1986 ainsi que 4 maquettes en trois dimensions. Quatre projets sont documentés par des maquettes tridimensionnelles : l'Université islamique de Madinah (1983), le Projet de conservation et de développement d'Abu Nuwas (1976), les Sancst Science Halls (1981) et les quartiers généraux d'Etisalat (1986). Le fonds contient également des soumissions de concours et de la documentation sur le développement de projets (1976-1987), reliés en 43 volumes. Neuf exemplaires de trois livres publiés contiennent également des études sur le travail et la carrière d'Erickson. Le fonds contient également la correspondance et d'autres documents d'Erickson.

The fonds consists primarily of Logan's scientific work. A small percentage relates to the affairs of his family and to memorials to Logan after his death. The great majority of the papers consists of scientific correspondence from about 1820 to 1874, but mostly for the years following his appointment to the Survey in 1842. The letters deal with the collection, exchange and description of geological specimens, expeditions under the aegis of the survey, problems of research and scientific interpretation, scientific meetings, and visits by scientists. The number of correspondents, both individuals and learned societies, is very large, but the most substantial bodies of letters are from J.W. Dawson, geologist and Principal of McGill University, James Hall, paleontologist of the New York Geological Survey, Alexander Murray, Logan's chief assistant, and James Lowe of Grenville, Québec, who supplied Logan with specimens and appears to have been casually employed by him on surveying jobs and field trips. Other correspondents include Sanford Fleming, E.D. Ashe of the Québec Observatory, Thomas Sterry Hunt, and R.I. Murchison of the Geographical Society of Great Britain. Some letters pertain to political or social affairs, but usually in close connection with the scientific work of Logan or the Survey. These files contain copies of some of Logan's outgoing letters, as well as some letters addressed to other individuals, generally his assistants. Other scientific papers consist of field trip records (a journal kept during an expedition in 1845, a weather table kept on Lake Superior in the winter of 1846-1847, work records and astronomical readings for surveying projects, notes on mineral deposits, and lists of specimens), manuscripts of three scientific papers, as well as "Observations on the proposed Geological Survey", and manuscript and printed maps and geological schemata, including some by Logan of the Bay of Fundy, Labrador, and Hamilton, Ontario regions. Manuscript catalogues of specimens were prepared by Logan for the Paris Exhibitions of 1855 and 1867. Official reports include Logan's annual reports for 1842-1844, an overview of the work of the Geological Survey, 1866, two reports by Logan on prospects for mining on the north shore of Lake Superior, 1846, 1847, and one on mineral deposits around Rivière-du-Loup, 1853, as well as Logan's copy of his proposed Geological Survey Bill, 1844, and some copies of reports on mining and cartography prepared by others. Logan's financial records include expense accounts for Geological Survey expeditions, as well as other professional expenditures, such as books. His private and family life is reflected by a very brief diary of an Atlantic crossing in 1856, letters to and from his brothers James and Henry, his father, his uncle Hart Logan, and Hart Logan's partner John Fleming, covering the years 1772-1856. There are also baptismal and burial certificates, and legal documents, particularly bills of sale pertaining to James Logan's farm. Memorials to Logan after his death include J.W. Dawson's correspondence concerning the Logan Memorial Fund and Collection, 1881, and a manuscript biography by Alexander Murray. There is a chronological and author/recipient index to these papers.

Additional materials received from McGill Library's Rare Books and Special Collections consist of correspondence, 1837-1871; notices of admission to scientific and historical societies, 1842-1867; a history of the geological survey 1850; a report on mining locations addressed to B. Papineau, 1847; and correspondence with Robert Bell, 1861-1874.

The fonds contains original and typescript letters, manuscript notes, newspaper clippings, journal extracts, reminiscences and more, assembled by Harvey Cushing chiefly between 1920 and 1924 during the course of his research for the biography of William Osler. For the biography, Cushing collected and retyped over 7500 pieces of Osler's correspondence, among which are some original letters.

The fonds is separated into three series: Manuscripts, Working Notes and Osler's Correspondence. It also contains photographs, annual reports, publications, clippings, one watercolor painting, one postcard. Osler's correspondence is further arranged in three subseries based chronologically.

Fonds consists of Dr. Ewen Cameron's teaching materials, articles, addresses, and a file of material regarding the Nazi leader Rudolf Hess and his claims of amnesia during the Nuremberg trials in 1946, as well as a couple files of biographical interest on Cameron. Teaching materials consist of notes for a seminar on tension and anxiety for military psychiatric personnel (1943). Articles and addresses comprise a draft, with letter from the McGill Medical Journal, an article on psychiatric education (1944) an address to the American Psychiatric Association on day-hospitals (1947), opening remarks for the World Congress of Psychiatry meeting (1961), and "Some thoughts on my years as director of the (Allan Memorial) Institute" (1964). There are also a few reprints of articles on memory, psychiatric training, and hospitalization. The file on Rudolf Hess contains trial transcripts, examination reports, Cameron's contemporary notes on Hess's condition, and some later comments on and correspondence about the proceedings (1945-1947). Biographical materials consists of a copy of Cameron's letter of appointment at McGill (1943), and a biographical sketch by Dorothy Trainor of the Allan Memorial Institute.

The Sir William Osler Collection, distinct from the Bibliotheca, is an extensive archival holding of Osler's correspondence (including eighteen hundred original letters), daybooks, accounts, engagement books, legal documents, book invoices, membership certificates, notebooks, lectures, addresses, newspaper clippings, photographs, books with manuscript additions, and miscellaneous loose items formerly inserted into individual books in his library. The collection also contains various family papers, including correspondence of Lady Grace Revere Osler and Edward Revere Osler.

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.
