I tried to find some plausible examples of archival records in library catalogs, but nothing seemed to fit your case. Part of this is due to the way the location field works in MARC records. The actual MARC location includes the institution, the branch, and then the shelf location of the item. So if your "archive" refers to the institution, then it would fit as part of the location. If so, I suspect that you'd like separate coding for the institution and the shelf location, which is the case in MARC but not in MODS. The MARC style makes it possible to do this kind of display: UC Berkeley Bancroft Library H123.B3 As for the "collection" -- I've seen this listed as a series title in a number of library records, but many times the MARC record is for an entire collection ("The Mark Twain Papers") so the collection ends up being the title. That said, I don't think that you want to list the location within host -- you're really talking about the location of the item itself. So if the "host" refers to the collection, you could do: <titleInfo> <title>Your Liberties</title> </titleInfo> <location> <physical location>ACLU Library, MC#001 Box 1124 Folder 8</physicalLocation> </location> <relatedItem type="host"> <titleInfo> <title>American Civil Liberties Union Records</title> </titleInfo> <typeOfResource collection="yes">mixed material</typeOfResource> </relatedItem> or, using the host location as the location of the archive: <titleInfo> <title>Your Liberties</title> </titleInfo> <location> <physicalLocation>ACLU Library, MC#001 Box 1124 Folder 8</physicalLocation> </location> <relatedItem type="host"> <titleInfo> <title>American Civil Liberties Union Records</title> </titleInfo> <typeOfResource collection="yes">mixed material</typeOfResource> <location> <physicalLocation>ACLU Library, NY, NY</physicalLocation> </location> </relatedItem> kc On Wed, 2004-02-18 at 11:03, Bruce D'Arcus wrote: > On Feb 18, 2004, at 8:10 AM, Andrew E Switala wrote: > > > Looks like <location>, from the examples for MARC field 852 at > > http://www.loc.gov/marc/bibliographic/ecbdhold.html#mrcb852 > > Hmm...you're probably right, but this just doesn't seem right to me: > > <physicalLocation>Seeley G.
