It may be appropriate, after one or more bibliographic records have been cataloged, to change the cataloging decision (e.g., recatalog a monograph as a serial). See the section “Change in Cataloging Decision” for guidelines. Also, a publisher may change the type of issuance of a bibliographic resource. See the last section, “Change in Type of Issuance,” for guidelines.
