Happy New Year Mapsters! I am trying to make a decision about the fate of our collection of Airport Obstruction Charts (OC Seris). Obviously this material is date sensitive and it seems that it was discontinued 5 or 6 years ago. Has this information been replaced by some other form of publication? It looks like the closest thing that may have replaced the Obstruction Charts is the US Terminal Procedures Publications. If so, then I can discard the OC's. If anyone has any information on this I would be most grateful. ___________________________ 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
