----------------------------Original message---------------------------- 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.
