LC-PCC policy statements for absorption of expression

LC/PCC practice: Since a diachronic work is realized by one and only one expression and embodied by one and only one manifestation, do not use this element to express relationships between diachronic works. Use instead the equivalent element under the RDA entity Work.

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.
