     I just noticed that the USGS "I" series seems to have a new series
     name.  For decades this has been known as the MISCELLANEOUS
     INVESTIGATIONS SERIES.  I received USGS I 2616 and this is now their
     GEOLOGIC INVESTIGATIONS SERIES.
 
     The USGS already has a GEOLOGIC QUADRANGLE SERIES "GQ"; why does the
     world need a GEOLOGIC INVESTIGATIONS SERIES?
 
     Thanks for any clarification.
