What are collective language codes?
Collective language codes are language groups that are used if the criteria for assigning a separate language code are not met. The words “languages” or “(Other)” indicates that a language code is a collective one. ISO 639-1 does not use collective codes, but ISO 639-2 does. References from separate language names to the collective code used for that language are not included in the ISO 639-2 standard, but may be found in the MARC Code List for Languages.
