When editing a biblio record, you can launch a builder plugin for 008. Positions 15 to 17 hold a two- or three-character alphabetic code that indicates the place of publication, production, or execution. There is a link to a MARC Code List for Countries Positions 35 to 37 hold a three-character alphabetic code for language. There is a link to a MARC Code List for Languages. It would be helpful if these codes were available as authorised value categories, to prevent user typing error.
