The British Library was created in 1973 by the "British Library Act 1972". Since 1997 the main collection has been housed in a single new building on Euston Road next to St. Pancras railway station. In the middle of the building is a four-storey glass tower containing the ‘’King's Library’’, with 65,000 printed volumes along with other pamphlets, manuscripts and maps collected by King George III between 1763 and 1820.
