     There have been several examples lately of the USGS lettered series
     maps (in the envelopes) being "reprinted." That's what it actually
     says on the envelope. How is the rest of the map cataloging world
     treating these? As reprints and creating a new record separate from
     the original publication? Or - as a printing and not creating a new
     record? If not creating a new record, do you add just a 300 subfield g
     to the record for the original publication? Or do you just consider
     the "reprint" a second copy of the original? Anyone with advice? LC?
     USGS? I usually don't have the original publication so I can't compare
     the two.
