Artist Rooms is the title of a collection of international modern and contemporary art, established through the d'Offay donation in 2008. Comprising over 1,500 works by 38 artists, it is owned by the National Galleries of Scotland and the Tate, on behalf of the United Kingdom, which care for the collection together and arrange for its presentation throughout the country in museums, galleries, and exhibition spaces. Each "room" is devoted to a specific artist with the aim of providing an immersive and comprehensive experience of that artist's work, a format described by Nicholas Serota as being "without precedent anywhere in the world."
