Andreassen's papers fall into three series: personal materials, diaries, and professional files. Personal materials include family correspondence, 1929-ca 1932, and ca 30 cm of class notes and draft papers stemming from his student years, largely at Louisiana State. There are also files of private correspondence, some addressed to Mrs Andreassen, from the period 1975-1980. Andreassen's diaries cover the years 1936-1940, 1945-1952, 1962-1965, and 1968-1976. They record the working day and are interleaved with memoranda and correspondence, often of a personal nature. Professional files vary in nature with each stage of Andreassen's career, but correspondence and reports are consistent elements. To these may be added copies of surveys and inventories of the Louisiana Historical Records Survey, expense accounts and photographs arising from his work for UNRRA, records of archival deposits and drafts on an institutional history prepared as Archivist of CNR, and annual reports written as McGill Archivist.

Lochhead's papers comprise 20 pages of notes on the relationship of ferns and bryophytes, and a volume of notes of Sir William Dawson's lectures in ordinary and honours geology courses.

The fonds consists of mostly administrative functions. Organized by year of its donation to McGill. It consists of the club’s constitution, correspondence, financial statements, bonds, annual dues, cash receipts, minutes, speeches, photographs, pamphlets. Invitations, meetings, lists of committee members, speakers, annual reports. These represent the main functions of the organization and its members.

The content ranges from low level administration such as the meeting minutes and invitations to high level administration functions such as financial reports and bonds. These illustrate the daily function of the club in organizing meetings and luncheons at hotels, as well as correspondence with members. There are photographic materials of speakers at the luncheons.

Hemlow's teaching activities are documented by her students' examination papers in Mediaeval, Renaissance and 18th century literature for 1941, 1948 and 1953.

Most of this archive documents the High School for Girls. The administrative records comprise prospecti for both High Schools, registers of attendance, 1875-1896, examinations, 1855-1858, 1884-1888, fees, 1863-1869, and corporal punishment, 1892-1896, 1949-1960, and memoranda from the Rector applying to either the boys' division or to both High Schools, 1897-1904. There are also working notes for teachers, 1902-1903, 1921-1931, and scrapbooks of programmes, clippings and notes concerning activities in both schools, covering the years 1913 to 1960. Examination papers, 1872-1882, a guest book, 1919-1943, an annotated address book of High School for Girls staff prepared by Principal L.M. Hendrie, 1911-1945, and photographic portraits of the Principals of the High School for Girls round out this series. Student activities are reflected not only in the official scrapbooks, but also in minute books, photograph albums and scrapbooks of the High School for Girls' Athletic Association, 1912-1913, Literary and Debating Society, 1906-1908, and English Club, 1935-1940. There are a large number of photographs of girls' sports teams, 1915-1941, as well as a scrapbook of clippings on the activity of High School for Girls Alumnae, 1953-1956.

Fonds contains correspondence and manuscripts. The correspondence is largely devoted to the Tait family’s property in Nova Scotia and other domestic matters, but there are also files regarding Tait’s work at McGill (1928-1942) and at the Nova Scotia Summer School in Education (1927-1941). The fonds also contains a few letters to and from Vincent Massey (1926-1940). Approximately a third of Tait’s papers are drafts of publications on practical psychology, behaviour and behaviourism, educational psychology, psychopathology and social applications of psychology. (ca 1920-1930).

Fonds consists of original files and printed materials falling into two themes. The larger of the two concerns Pavlasek’s work on the Superior Council of Education (1967-1972). Correspondence, notes and minutes deal with the establishment of the Université du Québec, the organization of a Council of universities, and legislation regarding capital funding of universities. The McGill Senate is the subject of the second group, comprising correspondence, minutes, reports and submissions from 1963 to 1971.

Fonds reflects Jones’ work as a scientist, but not her activities as a poet. Over two-thirds of the materials are student notes coupled with quizzes, laboratories and reports. These largely stem from her Cornell period, and cover graduate seminars in population genetics and biochemistry as well as her doctoral research in plant breeding and plant physiology. There are also notes for courses on statistics, genetics, agriculture and animal physiology from the University of the West Indies.

Materials related to Jones' research comprise laboratory notes and graphs, drafts of papers and correspondence with publishers, scientific supply companies, and other scientists in her field. Administrative papers related to research include applications to the National Research Council, budget statements, requisitions and invoices for equipment, records of laboratory assistants and summer students, and correspondence on travel arrangements.

Her teaching of genetics and zoology is illustrated by her class and seminar notes, laboratory outlines, reading lists, and examinations. The administrative side is represented by memoranda on course changes and course evaluations, correspondence on the rental of films and the purchase of equipment, files on freshman counseling and the supervision of graduate students and letters of recommendation for students. Supplementing this are minutes of faculty meetings and materials relating to the McGill Association of University Teachers.

Biographical material on Jones may be found in a file containing curricula vitae, obituaries, and correspondence concerning the Barbara Jones Fund.

The Canadian Officers’ Training Corps, McGill Contingent Fonds consists of two series: historical records and administrative records. The majority of the historical records consist of scrapbooks containing mostly news clippings and personal correspondence (1914-1962). One part, covering 1914-1917, consists of news clippings on the C.O.T.C. and the 148th Battalion.A second group of historical scrapbooks and records begins in 1914 and continues through to 1939. Besides press clipping, these scrapbooks contain photographs, orders, invitations, copies of pamphlets, and other records such as the log book of the Ski Camp, 1935-1936. These scrapbooks were the model for the 8-volume Historical Record of the C.O.T.C. during World War II. These volumes contain a running chronology, orders, press extracts and clippings, statistics, photographs and personal reminiscences. The last volume is a service record of all C.O.T.C. members. These are supplemented by two news clippings scrapbooks for the period 1939-1942. A "Book of the Six Universities Companies'' of the Princess Patricia Canadian Light Infantry was prepared for the unveiling of a memorial plaque after World War II. It contains a historical record and statistics. Other historical files include printed records of the 148th Battalion, correspondence, programmes for the 1962 celebration of C.O.T.C.'s 50th anniversary, and miscellaneous Christmas cards, invitations, programmes, recruiting and activities booklets, and standing orders. The administrative records are composed mostly of minutes, with some reports and official letters (1941-1959), as well as Commissions for Lieutenants (1915-1916), directories and roll calls (1917, and 1939-1949), handbooks (1916), and orders (1914-1929). Also found in the fonds are some scattered periodicals (1915), religious texts (1914), a souvenir book (1918), speeches (1920), photographs, and stationery.

Fonds consists of correspondence, research and genealogical notes, articles produced by Evelyn Miller's activities as a researcher, historian, writer and archivist. There is also a considerable amount of primary source material collected by Evelyn Miller on her family; particularly correspondence, sermons and articles relating predominately to Abraham de Sola but also to David Aaron de Sola (Abraham's father), Aaron David Meldola de Sola, Clarence Isaac de Sola and the Hart family. The fonds have a vast amount of photographs mostly of the de Sola Family, but also the David, Hart and Joseph families. The fonds is composed of the following series:

1. Original Historical Records (de Sola, Hart, Joseph) Documents
2. Research and Professional Activities

Although there are two separate series, it must be noted that some information contained in the series files are often relevant to more than that area of activity. This is especially true of correspondence files.
