----------------------------Original message---------------------------- Hello, After receiving a new USGS I-map today (I-2544) with the Miscellaneous Investigations Series title on it (rather than Geologic Investigations Series), I decided to go and check on the Geologic vs. Miscellaneous Investigations maps on the shelf. According to the Administrative Notes supplement, the Geologic Investigations Series starts with I-2522. However, I have found 23 Miscellanous Investigations after I-2522, compared with 12 Geologic Investigations. Some of the Miscellanous Investigations are dated 1997 (I-2522 was published in 1996). Can someone clarify this matter? Will the series continue to be split between titles, or will they all eventually be the Geologic Investigations series? ************************************************************************ * Linda Zellmer Phone: (602) 965-5973 Map Librarian Fax: (602) 965-0883 Arizona State University Libraries EMail: [log in to unmask] P.O.
