The fonds consists of the correspondence series, which is all that remains of the records of the Department of Agronomy. During its early years, the Department concentrated mostly on public education and outreach, and the material reflects this, for it includes a large number of inquiries from local farmers and gardeners regarding their crops. It is arranged in an identifiable classification system that is consistently used and developed throughout the years.

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.
