The British Library is the national library of the United Kingdom, and one of the world's largest libraries in terms of total number of items. The library is a major research library, holding over 150 million items from every country in the world, in virtually all known languages and in many formats, both print and digital: books, manuscripts, journals, newspapers, magazines, sound and music recordings, videos, play-scripts, patents, databases, maps, stamps, prints, drawings. The Library's collections include around 14 million books (second only to the USA's Library of Congress), along with substantial holdings of manuscripts and historical items dating back as far as 2000 BC.
As a legal deposit library, the British Library receives copies of all books produced in the United Kingdom and the Republic of Ireland, including a significant proportion of overseas titles distributed in the UK. It also has a programme for content acquisitions. The British Library adds some three million items every year occupying 11 kilometres of new shelf space.
The library is a non-departmental public body sponsored by the Department for Culture, Media and Sport. It is located on the north side of Euston Road in St Pancras, London (between Euston railway station and St Pancras railway station) and has a document storage centre and reading room at Boston Spa, Wetherby in West Yorkshire.
