The O’Brien Library

The O’Brien Library, named in honor of long-time librarians Elmer J. and Betty A. O’Brien, features a circulating collection of over 100,000 volumes maintained in open stacks on the campus of United Theological Seminary. In addition, the library houses a reference collection, rare books collection, denominational collections, and archival materials. In 2020, the O’Brien Library joined the Digital Theological Library (DTL) to provide United students and faculty with expanded access to digital resources. While DTL use is limited to current students and faculty, the Open Access DTL catalog is available for everyone, providing free access to over 120,000 eBooks and other online resources (for more information, click here.)
