University of Oxford
The university maintains the largest university library system in the UK, and, with over 11 million volumes housed on of shelving, the Bodleian group is the second-largest library in the UK, after the British Library. The Bodleian is a legal deposit library, which means that it is entitled to request a free copy of every book published in the UK. As such, its collection is growing at a rate of over three miles (five kilometres) of shelving every year.
