Fonds consists of records which reflect Brink's participation on the Environmental Assessment Panel (1973-1983) and The Nature Trust (1984-1987). The papers include material arranged in the following series: correspondence, teaching and research. The papers also include reference booklets and pamphlets. Each series is arranged in chronological order. The records primarily contain one large correspondence series from 1953 to 1975, with bulk dates of 1961 to 1971. The correspondence contains Brink's faculty papers intermingled with the Division of Plant Science's central office files.

The fonds consists of correspondence, lecture notes, reference clippings, student notebooks, programs, newsletters, certificates, musical scores, receipts, pamphlets, and books produced and received by Wilfrid Sadler during his student days at Macdonald College and his professional activities as a professor in the Department of Dairying from 1918. The Department of Dairying was part of the Faculty of Agriculture from 1916 to 1955.

The fonds consist of lecture notes and other course materials, manuscripts, correspondence, and published materials produced and received by Boving during his professional activities as a professor of agronomy. It is arranged in three series, plus a separate adult education reference file. The records are arranged in alphabetical or chronological order. Occasionally Boving has identified subject categories.
