Language
The language of cataloging is English. Though bilingual and multi-script records are supported by the Koha system, it is optional to produce bilingual or multi-script records and the requirement for a translation will be determined on a case-by-case basis, based on the type, specifics, and language of the documents.
For language codes use ISO 639-1 Codes for the representation of names of languages - Part 1 : alpha-2 code.
For additional guidance please see the OSA Language Policy, found in Appendix B.
