Many institutions have collections of art images, on slides or in digital format, typically organized by period, country, or medium. Such collections can provide visual resources for study and presentations. However, many image collections are maintained by the art department rather than the library and may have restricted use. To locate sources for art images, consult the Image Buyer's Guide, 7th ed. (Englewood: Libraries Unlimited, 1999).
