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.
