Looks like <location>, from the examples for MARC field 852 at http://www.loc.gov/marc/bibliographic/ecbdhold.html#mrcb852 >>> [log in to unmask] 2004-02-17 17:14:19 >>> OK, am working with archival documents, and am stuck on how to deal with the collection info. I've got: 1) the archive 2) the collection 3) the folder and box info The collection is easy: just the title on relatedItem "host" with a typeOfResource collection value of "yes." 3 goes in location (though I suppose could be thought of as belonging to part?). Where does 1 go? As a corporate name with a role? As a part of the location? As a publisher? Here's where I'm at there: <relatedItem type="host"> <titleInfo> <title>American Civil Liberties Union Records</title> </titleInfo> <typeOfResource collection="yes">mixed material</typeOfResource> <location> <physicalLocation>MC#001 Box 1124 Folder 8</physicalLocation> </location> </relatedItem> Bruce
