Congregational Library and Archives

The Congregational Library’s collection of some 225,000 books, pamphlets, periodicals, and archival sources documents the growth and development of this important American spiritual tradition, from Puritan times through the twentieth century. Its collection of first-generation American Puritan sources is unusually broad and unique, and is supplemented by a large and growing collection of seventeenth and eighteenth-century church records. The Congregational Library has a strong representation of New England town and county histories, reports from foreign missionaries, some 15,000 sermons, and a full archive of the denomination’s progressive social program in the twentieth century.
