Chieko,
Thank you so much! I have accepted offers for both hardcopy indexes and
having a hardcopy index scanned and sent to me on CD. So, now I can
accept these files for future use too! Our brand new map librarian,
Marcy Allen, starts next week here at PSU and she has some GIS skills so
maybe she can take this data and work towards both updating the
information and enriching it. Getting your indexes mounted on one or
more of the map organizations, when they are ready, would be really
helpful to folks I'm sure, even map catalogers like me who sometimes
would like to determine what "pieces" of a set or series we lack
locally. Thanks for your help!
Paige
