National Library of Scotland

The National Library of Scotland (Scottish Gaelic: Leabharlann Nàiseanta na h-Alba, Scots: Naitional Leebrar o Scotland) is the legal deposit library of Scotland and is one of the country's National Collections. It is based in a collection of buildings in Edinburgh city centre. The headquarters is on George IV Bridge, between the Old Town and the university quarter. There is also a more modern building (1980s) in a residential area on the south side of the town centre, on Causewayside. This was built to accommodate some of the specialist collections (e.g., map library, science library) and to provide large-scale extra storage.

The National Library of Scotland holds 7 million books, 14 million printed items and over 2 million maps. The collection includes copies of the Gutenberg Bible, the letter which Charles Darwin submitted with the manuscript of Origin of Species, the First Folio of Shakespeare and numerous journals and other publications.
