Which MARC record field identifies the originating server?
Hi, I have been downloading MARC records asynchronously from multiple Z39.50 servers using Net::Z3950::ZOOM. I push them into an array as they arrive. When I later examine the records, I'd like to be able to identify which library server each record came from. Does every MARC record contain a field/subfield that identifies the library the record came from? Field 040 seems only to identify the organization that originally created the record, which may be different from the library whose server I downloaded the record from. If there is no such field for every record, I'll have to tag the records as they come in, but I suspect this will slow down the downloading process. Many thanks! - Chris Morgan

There is no way to reliably determine which Z39.50 server a MARC record came from just by inspecting the record. You'll have to record the source as you process each ZOOM event.

Bryan and Galen, Many thanks! I'll just tag the records as they come in. - Chris -Original Message- From: Galen Charlton [mailto:[EMAIL PROTECTED] Sent: Tuesday, April 08, 2008 5:33 PM To: Christopher Morgan Cc: perl4lib@perl.org Subject: Re: Which MARC record field identifies the originating server?
