When to create a new bibliographic record for music

Music Cataloging at Yale General music cataloging resources

Note: this page was created with music cataloging in mind.

See also When to input a new record from OCLC and Guidelines for determining proper format for scores and score-like material

The information in this document was extracted from the ALA document: Differences Between, Changes Within: Guidelines on When to Create a New Record, which was derived from AACR2. The information on this page refers to single-part and multipart monographs, but not to integrating resources or serials. For complete instructions and information, see the document.

The decision to create a new record is based on major vs minor changes or differences:

A change: a manifestation has been altered in a manner that requires editing of the bibliographic record describing the manifestation.
     The document does not define "significant change"
A difference: a disparity between two or more resources.

° When there is a MAJOR change or difference, create a new record.
° When there is a MINOR change or difference, do not create a new record;
     ° instead, modify the existing bibliographic record or use the record as is.
° Generally, multiple MINOR changes or differences do not add up to a MAJOR difference.

Cataloging rules

° For all formats except continuing resources: If a record created according to either AACR2 or RDA already exists in WorldCat, do NOT create a duplicate record according to the other code.
