----------------------------Original message---------------------------- 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. - Paul Leverenz Scripps Institution Oceanography
