The Durham University Library is the centrally administered library of Durham University in England and is part of the university's Library and Collections department. Its two main libraries are Palace Green Library and the Bill Bryson Library. It was founded in January 1833 at Palace Green by a 160 volume donation by the then Bishop of Durham, William Van Mildert, and now holds over 1.6 million printed items. Since 1937, the university library has incorporated the historic Cosin's Library, founded by Bishop Cosin in 1669. Cosin's Library and the Sudan Archive held at Palace Green Library are designated collections under Arts Council England's Designation Scheme for collections of national and international significance; two collections at Durham University Oriental Museum, the Chinese collection and the Egyptian collection, are also designated.
