Duke Humfrey's Library is the oldest reading room in the Bodleian Library at the University of Oxford. Until 2015, it functioned primarily as a reading room for maps, music, and pre-1641 rare books; following the opening of the new Weston Library, it is now an additional reading room for all users of the Bodleian, as the Weston Library operates a reading room for special collections.[1] It consists of the original medieval section (1487), the Arts End (1612), and the Selden End (1637).
