Art libraries are plural entities in that they have multiple functions and serve a variety of users. In the United Kingdom, as elsewhere, academic art libraries provide visual resources for artists and art students; they also provide a wide range of texts for students of increasingly specialised branches of the history of art and design and of ‘visual studies’. Their librarians should collaborate with academic colleagues to develop the library to serve the institution’s needs; at the same time the institution should recognise the role of the library. The broader spectrum represented by the ‘new art history’ challenges the art library to widen its scope, although this must be done through networking as well as by means of collection development. Scholars realise that they must generally expect to have to go to the major libraries and archives for primary source material, although smaller art libraries often have valuable materials and some scholars might be encouraged to share their own research collections through the libraries of their institutions. Information technology has become the key to tracing material, but is no substitute for direct interaction with the materials themselves.
