The British Museum is a public museum dedicated to human history, art and culture located in the Bloomsbury area of London. On 7 June 1753, King George II gave his royal assent to the Act of Parliament which established the British Museum. The British Museum Act 1753 added two other libraries to the Sir Hans Sloane collection, those of the Cottonian Library, assembled by Sir Robert Cotton, dating back to Elizabethan times, and the Harleian Library, the collection of the Earls of Oxford. They were joined in 1757 by the "Old Royal Library", now the Royal manuscripts, assembled by various British monarchs.
