The NLS is one of the UK's deposit libraries, entitled to request a copy of every printed item published in the UK and Ireland. It contains around 14 million printed items, 25,000 newspaper and magazine titles, more than 100,000 manuscripts, and rare books dating to the 16th century (including the first ever printed Scottish history book, Scotorum historiae a prima gentis origine). Items can be viewed on here for research purposes, or in the Causewayside building in South Edinburgh, for those 'requiring material not readily available elsewhere'. Admission is by ticket, for which ID is required. Sporadic exhibitions cover various Scottish themes.
