The National Library of 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.
