What are collective script codes?
Collective script 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 15924 does not use collective codes, but ISO 15924 does. References from separate language names to the collective code used for that language are not included in the ISO 15924 standard, but may be found in the MARC Code List for Languages.
