ABSTRACT
One significant asset of the Internet for art researchers is the ability to investigate various libraries’ collections to discover material that has been written or compiled on a specific subject. Many libraries have Internet sites that provide search capabilities of their online public access catalogues or OPACs. Some are available through Telnet, others via the Web. This computerization of a library’s bibliographic holdings was made possible in 1968 when the U.S. Library of Congress developed LC MARC tapes, a library system capable of being used through computers. This made it easier for libraries to develop their own online catalogues.
