Oh, and a small army of students helps too. ___________________________ Chris Mixon Library Assistant III Cataloging/Government Documents Unit Auburn University Libraries 231 Mell St. Auburn University, AL 36849-5606 Phone: 334-844-1759 Fax: 334-844-1703 E-mail: [log in to unmask] http://www.lib.auburn.edu http://www.auburn.edu http://www.nacis.org
