Andover-Harvard Theological Library holds more than 1,400 collections of archival material, including letters, diaries, photographs, and drafts.
As the official repository for the Unitarian Universalist Association, the Unitarian Universalist Service Committee, and Beacon Press, the collections are particularly strong in the Unitarian Universalist (UU) tradition, and also include UU ministers' papers and the records of UU affiliated groups.
Beyond the UU tradition, AHTL collects the papers of Harvard Divinity School faculty, select records of Harvard Divinity School, and the records of other religious organizations and individuals.
The categories below are five broad groupings of collections. To do a more comprehensive search of all of AHTL's archival collections, use the search box below in addition to an AHTL-targeted search on HOLLIS for Archival Discovery.
