These papers of Elisha Lord Cleaveland deal largely with his ministry in the Third Congregational Church of New Haven, Connecticut, from 1833 until his death in 1866. Three quarters of the papers consist of sermons by Cleaveland in a series numbered up to 1,402; approximately 1,300 are preserved here. Other writings by Cleaveland include notes on various subjects, and a number of lectures, some bound in notebooks and apparently intended for use at Andover Theological Seminary.
Three diaries, a record of ministerial duties, and a journal provide insight into Cleaveland's ministry. All five volumes detail church activities, texts of sermons preached and heard, visits to parishioners, and so forth, as well as occasional personal matters such as his reading, his health, and visits to neighboring towns. Some family events are recorded, including the prolonged illness and death of his brother, John, in December 1863 (folder 4). While routine church duties form the bulk of the contents of these volumes, there are some unusual items. The record of ministerial duties provides an account of Cleaveland's visits to a condemned criminal and of his feelings while officiating at the execution (folder 3a, Jul 1846), and an account of a daughter's mystical experience (Feb 1848).
Other miscellaneous items contained here are: an account book of the Third Congregational Society of New Haven; a personal account book; clippings about the Third Society and copies of other newspaper articles; and a certificate recording Trumbull Cleaveland being made a church member.
