Documento BHH/1/70 - Letter from Josiah Forshall (1795 –1863), Secretary British Museum, to Brian Houghton Hodgson, 15 May 1845

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.

Sloane's collection, while including a vast miscellany of objects, tended to reflect his scientific interests.[16] The addition of the Cotton and Harley manuscripts introduced a literary and antiquarian element, and meant that the British Museum now became both National Museum and library
