----------------------------Original message---------------------------- Jenny, We've had Marcive tapes for over a year now. Our campus Computer Center loads the monthly tapes into the mainframe, but not always monthly. Its more like when they get around to it; when there's nothing more important to do. But that's a local problem. After the tape is loaded, I get a printout of all the map records. Its just a list of the GPO 8-digit numbers in the 035/1 field. We have records for all the USGS quads, aero- and nautical charts, etc. Our Marcive profile was set up so that a SuDoc number appears in the 099 field, and since the Map Collection uses LC classification, my student employees go in and change the 099 to the LC number. It took us a year to edit all the records for the topos going back to 1976. Since we keep the most recent edition only for most government maps, there are thou- sands of records to delete. Maybe by the time I retire we'll have a clean database... There's a one to two month delay between receiving the map and its record appearing in the OPAC. Since we like to get the maps into the collection ASAP, we have piles of cataloging slips sitting around until the records get processed. All in all, I'd say it takes at least .5 FTE to keep the database accurate, after the initial clean-up. Jim Coombs Map Librarian Southwest Missouri State University
