Reference materials can provide basic background information on your topic and help you identify keywords for further searching; for example, the names of important artists or art theorists, materials, or events. Some also contain topical essays that can be excellent introductions to a particular subject or time period.
Many reference resources provide bibliographies at the end of each entry or volume, which will point you to additional books, exhibit catalogs, and journal articles worth exploring.
Reference books in print are shelved by call number behind the Reference Desk on the Main Level of the library or downstairs in Lower Level Reference. They may not be checked out, but scanners and photocopiers are available on the lower level of the Library.
