 Also, as a result of the British Legal Deposit Libraries Act 2003, which continues a more ancient right dating from 1801, the Library is entitled, along with the British Library, the Bodleian Library at Oxford, Cambridge University Library, the National Library of Wales and the National Library of Scotland, to receive a copy on request of all works published in the United Kingdom.Many works are now being received electronically rather than in print under new UK regulations which came into force in April 2013.The main chamber of the Old Library, the Long Room, was built between 1712 and 1732 and houses 200,000 of the Library's oldest books.
