The Bodleian Library is the main research library of the University of Oxford and the second-largest library in the United Kingdom after the British Library. Founded in 1602, it houses over 13 million printed items. The historic buildings include the famous Duke Humfrey's Library with its ornate wooden ceiling and the stunning Divinity School. Scenes from the Hogwarts library and hospital wing in the Harry Potter films were filmed here. The Weston Library offers free exhibitions.
