The papers consist of McLennan's reminiscences of his Fairview days and life as a Rhodes scholar. Also included is a series of correspondence dating from 1924 to 1976. The correspondence has been arranged in two ways. The general correspondence has been simply arranged chronologically while other letters and cards, which McLennan sent to the Archives as identified groups, have been maintained as such. The papers also include printed material from the Canadian Association of Rhodes Scholars and Balliol College.
