 I have a DMA map with the number 6010 on it.  An index map on the bottom of th
 e sheet indicates that the whole world is covered by this series in 12 sheets,
 numbered 6000-6011 but there is no title for the series on the 6010 map or the
 index to sheets map. Does anyone know the title of this series?  I need it for
 cataloging the map.  SHeet 6010 covers southern South America and is revised 19
 74.
