The National Library of Scotland is one of the country's National Collections. It is one of the largest libraries in the United Kingdom. As well as a public programme of exhibitions, events, workshops, and tours, the National Library of Scotland has reading rooms where visitors can access the collections. It is the legal deposit library of Scotland and is a member of Research Libraries UK (RLUK) and the Consortium of European Research Libraries (CERL).

Legal deposit is a legal requirement that a person or group submit copies of their publications to a repository, usually a library. The number of copies required varies from country to country. Typically, the national library is the primary repository of these copies. In some countries there is also a legal deposit requirement placed on the government, and it is required to send copies of documents to publicly accessible libraries.
