Supplementary material includes pieces that are not indexes and that are issued in addition to the parent resource. Sometimes these pieces of supplementary material are clearly identified as supplements or as material supplementing the basic bibliographic unit. In other instances, the pieces are described in the bibliographic record as accompanying material, e.g., maps in pocket, an answer book accompanying a textbook, or a pamphlet accompanying an audio disc. Frequently supplementary material will be in a different medium from the parent resource.
Example 56: 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.
Holdings information for supplementary material that is not cataloged separately on its own bibliographic record is recorded in field 864 in the holdings record for the parent resource. The captions and publication pattern for field 864 are given in field 854.
Consumer reports issues a regular annual "Buyers' guide" as an extra issue. The reporting library holds v.1-13, 1951-1963 with Buyers guide for 1956-1962:
Holdings record:

Example 57: 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:
Holdings record:
853 20 |8 1 |a v. |i (year)
863 40 |8 1.1 |a 1-28 |i 1951-1978
854 00 |8 1 |a v. |b suppl.no. |i (year)
864 41 |8 1.1 |a 9 |b 1 |i 1959
Optionally, but not recommended:
Holdings data for supplementary material that has no enumeration and/or chronology or regularity may be recorded in subfield |a of field 867 in the holdings record for the related item.
867 40 |8 0 |a Has numerous unnumbered supplements
Example 58: Recording the type of supplement or the title of a supplement
Record the type of supplement in subfield |o of the 854 field.
Holdings record:
008/22-24: eng [language code English]
854 00 |8 1 |a (year) |b (month) |o Health supplement
864 41 |8 1.1 |a 1985 |b 06
The title of a specific supplement can be recorded in subfield |o of the 864 field.
Holdings record:
854 00 |8 1 |a (year)
864 41 |8 1.1 |a 1987 |o Fruits in the home garden
864 41 |8 1.2 |a 1989 |o Pine cones for everyday use
Subfield |o need not be defined in the 854 field to be used in the 864 field. Subfield |o may be used in both the 854 and the 864 fields of a holdings record.
Holdings record:
854 00 |8 1 |a v. |o plates
864 41 |8 1.1 |a 3 |o Istanbul
864 41 |8 1.2 |a 3 |o Istanbul's suburbs
Note: The HOLLIS user interface currently displays either 854 subfield |o or 864 subfield |o, but when both are present, HOLLIS displays only the 864 subfield |o. Code records correctly in anticipation of correct display generation in the future.
Optionally, information that a supplement is issued in more than one volume may be coded in subfield |z of the 864 field when those volumes lack their own designations.
