Hello, I'm a Koha newbie and unfamiliar with MARC (although I am a believer in using any available standards/practices). I have made some changes to what installer.pl has given for the "Links Koha - MARC DB", and thought I should share them with the group in the hopes that if I was doing something unwise, someone might warn me: biblio.unititle was mapped to 246a (Title proper/short title) However, since 246a is Repeating, I instead mapped bibliosubtitle.subtitle to 246a (Title proper/short title). My assumption in doing this was that bibliosubtitle.subtitle is a repeating field. Then I found that there was Non Repeating 240 Uniform Title, so I mapped biblio.unititle to 240a (Uniform title). Then I noticed 2 fields that appeared to repeat in the Koha DB which were not mapped, so I gave them the following mappings: additionalauthors.author = 700a (Personal name) bibliosubject.subject = 653a (Uncontrolled term) Part of the rational for using 653a is that we want to define our own internal set of "Authorised values" and then force our data entry volunteers to choose from that set of values. Thanks, Dave. -- Encrypted Mail Preferred: Key ID: 8527B9AF Key Fingerprint: E1B6 40B6 B73F 695E 0D3B 644E 6427 DD74 8527 B9AF Information: http://www.gnupg.org/ ASCII ribbon campaign: () against HTML email /\ against Microsoft attachments Information: http://www.expita.com/nomime.html
