Fonds concerns Forsey's activities as a student, and later as a teacher at McGill. Included are his fourth-year essay on Chaucer's Summoner's Tale, and his valedictory address (1925). His teaching career at McGill is documented by a file of correspondence, memoranda, and examination papers relating to one of Forsey's students in 1939, and files of correspondence concerning Forsey's reappointment in 1940 in the light of accusations, from various quarters, of Communist sympathies. Two letters from Forsey (1973, 1980) illustrate his later perspective on these events.

Fonds consists of papers pertaining to Gillett’s publications (with the exception of We Walked Very Warily), her addresses, the editing of the McGill Journal of Education and the functions of the Faculty of Education. Materials related to her publications include notes, drafts, galley and page proofs for A History of Education, Foundation Studies in Education, Educational Technology, The Laurel and the Poppy, and A Fair Shake: Autobiographical Essays by McGill Women (edited by Dr. Gillett and Kay Sibbold). There are also some photocopies, correspondence, and copies of photographs collected for We Walked Very Warily. Her editorship of the McGill Journal of Education is documented by copies of minutes of the Editorial Board (1966-1976), correspondence on funding (1970- 1971) and with contributors (1967-1971), and files of correspondence, manuscripts and proofs for issues from 1971, 1973 and 1974. A file of addresses together with some reviews, largely on the women's movement (1975-1976), her convocation address in 1971, and her Report on Women in the Montréal Area delivered at the National Conference on Women in the University, 1973 are also included. Finally, papers relating to her work at the Faculty of Education include correspondence, public relations and summer school materials (1963-1967), agendas, submissions and reports to the Senate of the faculty's Planning Commission (1972-1973) and files of the McGill Committee for Teaching and Research on Women, 1976.

Fonds are exclusively concerned with Hebb’s work as a research psychologist and professor. Hebb's research is documented by two types of material: his correspondence, and his files on research projects. Incoming and copies of outgoing letters from ca 1934 to ca 1977 are overwhelmingly scientific in character, discussing psychological theories and their criticism, research problems, the ethics of experimentation and funding. A second section of correspondence deals with learned societies and funding organizations (1959-1977). Project files contain reports to funding bodies, and, in particular, research files and reports for Defense Research Board projects, 1950-1962 (restricted); there are also files on the administration of research grants (1964-1973), largely dealing with appointments, payroll and travel funds.

Publications - his own, and others sent to him for evaluation - are the subject of correspondence with various publishers, 1950-1977. Files of notes, correspondence, reviews, and comments concerning Hebb's own books and articles cover the years 1933 to 1971. These papers also contains original drafts for 14 monographs, articles and speeches (1941-1959), including a draft of The Organization of Behavior with Karl Lashley's comments.

Course materials, and papers by and about his students, reveal Hebb's teaching activities. Lecture notes survive for about 120 addresses to seminars, colloquia and associations (1938-1976) and there are files of lecture notes, class materials and bibliographies for McGill courses, particularly "Introduction to Psychology" (Psychology 200). About 75 slides illustrate Hebb's addresses on "Thought and Language", "Semi-autonomous processes" and other topics (ca 1962-1972). Student materials consist of files of letters of recommendation and correspondence (1947-1977) with and about students, teaching assistants, and members of Hebb's research team. As well, there are 15 original and 4 volumes of photocopied undergraduate research papers (1959-1962) and copies of 42 graduate theses supervised by Hebb (1947-1972).
