Subfield $5 contains the MARC code of the institution or organization to which a note applies followed by any specific information about classification at the particular institution.  It is used for institution-specific information that may or may not apply to the universal use of the classification record.

See Appendix F for a listing of organization code sources used in MARC 21 records.
