Asked about how artists use libraries, art librarians confirm that artists gather ideas from a wide spectrum of subjects and sources, beyond the scope of the art library; they also need images and other, specific, information which art libraries often can supply. Their approach is typically exploratory and intuitive; they are compulsive browsers, but are likely to be impatient of catalogs and only occasional users of standard references tools. They expect a lot of help from specialist librarians. Art libraries serving artists generally provide access to a wide range of images, and invariably house their collections on open stacks. Photocopying, including color copying, is an essential service, and other visual and ‘studio’ facilities may also be provided. As more and more visual and other relevant information is made available through electronic networks, art libraries can provide artists with assisted, convenient access to it.
