"This basic list of Enhancement Terms for electronic photo archiving has its roots in the Library of Congress Thesaurus for Graphic Materials (1987 edition). A task force from the Special Libraries Association-News Division selected words from that list in 1994. Tribune Company news librarians refined that list, to which other newspapers, most notably the Columbus Dispatch and the Toronto Star and Sun, made additions. Another task force from the S.L.A. News Division considered all these changes and authorized this list, which was accepted by the S.L.A. News Division at its annual meeting in June, 1998."
