If the books you need are too far away, determine what interlibrary loan services are provided locally. Most public libraries participate in state and regional networks in order to borrow materials for their patrons.
The Kesler Circulating Library at Vanderbilt Divinity School sends books to ministers who do not have ready access to theological materials. Membership is open to any person in the continental United States or Canada who is engaged in ministry or retired from ministry. Register online for this free service.
