addressing one or more religious tradition(s); of those six, only three may be in the same tradition Harvard Divinity School Library (previously Andover-Harvard Theological Library) Library support for the study of religion at Harvard predates the establishment of the Divinity School; almost three-fourths of the 400 volumes that John Harvard gave to Harvard College in 1638 were theological in nature. Books on religion made up a third to a half of the college's holdings until the Divinity School was established in 1816 and duplicates from the College Library were combined with new purchases to form the beginnings of a specialized library for the school. In 1911, Harvard Divinity School and Andover Theological Seminary formed a partnership and agreed to house their collections together in a common library; when the educational partnership of the schools was dissolved in 1926, Andover Seminary's deposits remained in the library under the terms of a continuing agreement. The library's name changed from "Andover-Harvard Theological Library" to "Harvard Divinity School Library" in 2021. The library's collections include all religious traditions in order to support the many approaches to the study of religion at Harvard Divinity School. Its historical collection strengths include Protestant Christianity, Unitarian Universalism, and biblical studies. Additional areas of collecting emphasis since the second half of the twentieth century include women's studies in religion, the relation of religion to ethnicity and to LGBTQ studies, the ecumenical movement, interreligious communication, and religion and peace-making. Similarly, the rare book collection has strengths in early Protestant Christianity, Unitarian Universalism and related “nonconforming” traditions, and biblical studies. Notable special collections include the papers of Unitarian preacher and theologian William Ellery Channing, theologians Paul Tillich and H. Richard Niebuhr, and New Testament scholar Caspar René Gregory. Harvard Divinity School Library is part of Harvard Library, whose resources are available to all faculty, staff, and students at HDS. Harvard Library's collection has over six million digitized items, 20 million print volumes, 400 million manuscripts, one million maps, tens of millions of digital images, and rare and special collections. Harvard Library collects collaboratively with peer institutions and facilitates international open access, multiplying researchers’ access to materials. The HDS Library also participates in the Boston Theological Interreligious Consortium (BTI) library program, which extends borrowing privileges to HDS students and faculty at libraries of other BTI schools.
