The Bodleian Libraries are a collection of 28 libraries that serve the University of Oxford in England, including, most famously, the Bodleian Library itself, as well as many other (but not all) central and faculty libraries. As of the 2016–17 year, the libraries collectively hold almost 13 million printed items, as well as numerous other objects and artefacts. Its busiest library is the Social Sciences Library, which, at its peak, serves 7,500 visitors in a period of approximately nine weeks.
