58: Describing supplementary material with its own numbering
Supplementary material that bears its own enumeration and/or chronology can be cataloged separately on its own bibliographic record. In that case the holdings record for the supplement would not be attached to the main title’s bibliographic record but would attach to the supplement’s record. Information about the existence of a bibliographic record for the supplement is obtained through the linking fields in the main work’s bibliographic record field 770.

59: Describing supplements without their own numbering
Supplementary material that is designated as one of the regular issues (e.g., v.10:no.3) should not be recorded in separate 854/864 fields. This type of supplementary material is recorded in the 863 field like any other issue. A note in the subfield |z of field 863 may be used to give the specific location of the supplementary material. Supplementary material without its own enumeration and/or chronology, but with numbering related to a particular issue or volume of the parent publication is recorded in field 864, with the publication pattern in field 854.
In this example, the reporting library holds v.1-8, 1951-1958; v.9, 1959; v.9 supplement no.1, 1959; v.10-28, 1960-1978:
