The Book Library collections cover the history of art in the western tradition from classical antiquity to the present day. The holdings of the Library are estimated at some 140,000 titles, of which over 80,000 have accessible online catalogue records. The book stock comprises books, exhibition catalogues, permanent collection catalogues, sales catalogues, theses and dissertations, rare books and pamphlets and an increasing collection of material in digital and online format. Since its foundation in 1932, the Library has been enriched with major gifts by art historical scholars who have been associated with the Institute, such as Anthony Blunt, Michael Kitson, Count Antoine Seilern, and Johannes Wilde. Most of the stock is on open access to readers, including a collection of some 60,000 exhibition catalogues representing exhibitions on a broad range of topics from museums and galleries throughout Europe, North America, Australasia, and other parts of the world. Rare books, pamphlets, theses and dissertations are collected from the Closed Access Book Store (CABS) at regular intervals throughout the day.
