The Papers of John T. Kirkland, 1788-1837 and undated, chiefly document his activities as a Unitarian minister from 1794 to 1810 and as president of Harvard University from 1810 to 1828. The records include correspondence, letterbooks, notebooks, meeting minutes, diaries, commonplace books, sermons, and writings. A limited amount of material about Kirkland's student days at Harvard and his personal life are also included in the collection.
