Special Collections at Harvard Divinity School Library preserves and makes accessible primary source materials documenting the history of religion and theology, with particular historical emphasis on American liberal religious traditions. Though the historical strengths of the collections have been in the field of Christianity, other religious traditions are increasingly reflected, in step with Harvard Divinity School's evolving focus on global religious studies. Known as Andover-Harvard Theological Library since 1911, it was renamed the Harvard Divinity School Library in 2021.
