The Congregational Library & Archives is an independent special collections library and archives. It is located on the second floor of the Congregational House at 14 Beacon Street in the Beacon Hill neighborhood of Boston, Massachusetts. The Library was founded in 1853 by a gathering of Congregational ministers and has since evolved into a professional library and archives that holds more than 250,000 items, predominantly focused on 18th to 21st century American Congregational history. The Library's reading room is free and open to the public for research but the Library's stacks are closed and book borrowing privileges are extended exclusively to members.
