-------- Original Message -------- Subject: Latitude/Longitude Point display in MARC Date: Thu, 15 Jul 2004 16:28:25 -0400 From: Timothy Strawn <[log in to unmask]> To: [log in to unmask] CC: [log in to unmask] Dear Virginia: Although the 034 and 255 fields are repeatable, AACR2 and the Cartographic Materials Guide (AACR2 for Chapter 3) have specific requirements regarding the use of these fields --and 'listing' coordinate pairs for items within the bounds of a map is not a viable option for your needs. You are right --the information in 034 and 255 is for the map extent. The use of the 342 field as in your example is not accurate either (sorry for all of the bad news up front...) [The 342 will read: 342 02 Universal transverse Mercator $$p 17N4348491641488] The subfield p here Zones is used for celestial charts... Now --for the good news --but perhaps more work than you want it to be. First, I am assuming that the map includes many points which you wish to identify. IF the map is of a single mine (and therefore you need only record 1 set of coordinates) THAT IS a viable option with the standard use of the 034 and 255 fields and your problem is solved with the use of these two fields. I am assuming instead that you have a map with many locations (with different lat/long coordinates) you wish to record in the MARC record for the map. May I suggest that you use MARC field 552 "Entity & Attribute Information Note" ? Originally intended to describe digital geospatial data --it seems to be that it is a viable and appropriate field if we consider the Mine as an Entity and the mine location as one of the Attributes which comprise that Entity. (SEE MARC Concise Format for Bibliographic records at : http://www.loc.gov/marc/bibliographic/ecbdhome.html Specific info on the 552 field is than at: http://www.loc.gov/marc/bibliographic/ecbdnot2.html#mrcb552 So it might look something like this 552-1 __$aMine $b abandoned coal mine $c Location on the Earth's surface $eW 79°21'35''/N 39°16'34" (Always in West, East, North, South order) 552-2 __$aMine $b operational coal mine $c Location on the Earth's surface $eW 80°31'35''/N 38°16'34" Something like that. You can repeat the 552 for each lat/long location you would like to display on the MARC record for the map. You might check with your systems people on how fields will display in your OPAC. 5xx fields should display as notes, but since some of these fields are either new or have been modified in order to map geospatial metadata into the MARC format you want to make sure that they display properly to your users.
