purposed for visitors to consult maps, atlases, gazetteers, and cartographic reference books. The newest addition to the Library is the 2016 Kelvin Hall public centre in Glasgow, purposed to provide access to the library's digital and moving collections, namely the Moving Image Archive. Like at the library's main building, exhibits are held here too, though on a smaller scale. History Originally, Scotland's national deposit library was the Advocates Library belonging to the Faculty of Advocates. It was opened in 1689 and gained national library status in the 1710 Copyright Act, giving it the legal right to a copy of every book published in Great Britain. In the following centuries, the Library added books and manuscripts to the collections by purchase as well as legal deposit, creating a privately funded national library in all but name. By the 1920s, the upkeep of such a major collection was too much for a private body, and, with an endowment of £100,000 provided by Alexander Grant, managing director of McVitie & Price, the Library's contents were presented to the nation. The National Library of Scotland was formally constituted by Act of Parliament in 1925. Grant's support was recognised with a baronetcy, and in June 1924 he became Sir Alexander Grant of Forres. In 1928 he donated a further £100,000 – making his combined donations the equivalent of around £6 million today – for a new library building to be constructed on George IV Bridge, replacing the Victorian-period Sheriff Court, which moved to the Royal Mile. Government funding was secured which matched Grant's donation. Work on the new building was started in 1938, interrupted by World War II, and completed in 1956. The architect was Reginald Fairlie; the architectural sculptor was Hew Lorimer. The coat of arms above the entrance was sculpted by Scott Sutherland and the roundels above the muses on the front facade by Elizabeth Dempster. By the 1970s, room for the growing collections was running out, and other premises were required. The Causewayside Building opened in the south-side of Edinburgh in two phases, in 1989 and in 1995, at a total cost of almost £50 million, providing additional working space and storage facilities. Since 1999, the Library has been funded by the Scottish Parliament. It remains one of six legal deposit libraries in the United Kingdom and Ireland, and is overseen by a board of trustees. The Library also holds many ancient
