          Two publications are  in  question.  One  is  the  Map Cataloging
          Manual (30.00 US),  a  257 page, tabbed loose-leaf with 1991  the
          only  edition  thus  far published.   The  other  is  G  Schedule
          Classification for Maps (15.00 US).  Apparently, the  4th edition
          (1976) is the latest available.  Both may be ordered from:

          Hope this helps.
