The Congregational Library & Archives (CLA) is a thriving and internationally recognized independent research library in the heart of Boston. The CLA’s mission is to foster a deeper understanding of the spiritual, intellectual, cultural, and civic dimensions of the Congregational story and its ongoing relevance to contemporary society by collecting, preserving, and sharing materials and by actively engaging with scholars, students, faith communities, and the general public.

The CLA preserves and makes available materials pertaining to Congregationalism, the history of which has been interwoven with the development of the United States since the seventeenth century. The library and archives hold a rich collection of 225,000 archival and published materials, which have significance not only for church history, but also for American cultural, political, and social history, as well as family history. The CLA shares these materials freely by facilitating research in its reading room and offering virtual and in-person programs designed to explain the nature of the Congregational tradition, helping to illuminate and interrogate the faith’s national and global reach to inform the present and future.
