----------------------------Original message---------------------------- Hi all-- I'm working with an electronic formats cataloger in our Cataloging Division to catalog some CD-ROMs of GIS data (for example, 8 CDs of King County, Washington GIS data and 12 CDs of City of Seattle GIS data). Currently, I catalog only paper maps in the Map Collection...electronic format cataloging is done in our central Cataloging Division. These CDs contain many thematic data layers of GIS data, we think too many to do thematic subject headings (although we could probably do a few general ones like transportation, administrative and political divisions, hydrology, real property, etc.). Anyway, we are putting the following subject headings on the record for King County. Is this generally what other folks are doing? These CDs contain data only...no software. 651 0 King County (Wash.) |x Maps |x Databases. 650 0 Digital mapping |x Databases. (Wouldn't it be nice if this could be subdivided geographically?) We've also talked about responding to the request to find all "GIS data" in the Libraries catalog. Maybe a 655 genre/form entry? Like this?: 655 7 Geographic information systems data. $2 local Perhaps putting the "650 0 Digital mapping |x Databases" on every record would suffice for finding all the records. Any comments or other ideas? Thanks, Kathryn Kathryn Womble e-mail: [log in to unmask] Map Collection Phone: (206) 543-9392 University of Washington Libraries Box 352900 Seattle, WA 98195-2900
