LC-PCC policy statements for supplement to work

LC Core for serial relationships.

LC/PCC practice for serial supplements to other serials: Create a separate work for a serial supplement to another serial if the supplement does not update that related serial and carries its own designation system that is distinct and independent from that used by the related serial.

In addition, provide an authorized access point for the related serial unless the supplement has a common title that is identical to the title proper of the related serial. Other serial supplements should be noted on the metatdata description sets for the related serials. Provide access points for the supplement whenever the titles are distinctive.

See instructions below and refer to the Metadata Guidance documents on how to relate the works.

LC practice for supplementary materials: Create separate works for a main work and a supplementary work if the supplementary work is not issued at the same time as the main work, or if it shows important differences in titles or statements of responsibility from those appearing in the main work.

Also, catalog separately all supplements, etc., to serials except for:

1. Indexes, and
2. Supplements, etc., that have titles that are more like descriptions than true titles, or because the supplement, etc., is usable only in conjunction with the main work.

See instructions below and refer to the Metadata Guidance documents on how to relate the works.

LC/PCC practice: See the Metadata Guidance documentation: Descriptive Relationship elements and Relationship labels.

LC/PCC practice: Optionally, apply the instruction using a note.

LC/PCC practice: Record the element using a structured description. If possible, express the relationship using a relationship label, or a relationship label in combination with an identifier or IRI, as allowed by the metadata management system. Apply this policy statement when recording: 1) an authorized access point in a bibliographic record, 2) an authorized access point for a related entity in an authority record, or 3) a structured value that is not functioning as an access point. If the metadata management system does not permit recording a relationship label for the element, omit it.

LC/PCC practice: Apply the instruction. In most cases, give serial relationships as reciprocal relationships. See further instructions in the Metadata Guidance documentation on how to relate the works.
