Duke Humfrey's Library is the oldest reading room in the Bodleian Library at the University of Oxford. It is named after Humphrey of Lancaster, 1st Duke of Gloucester, who donated 281 books after his death in 1447. Sections of the libraries were restored and expanded in the 16th and 17th centuries, including the addition of a second storey, an east wing and a west wing. The library currently functions as a reading room.
