Modify the selected record to conform to AACR2, remembering that this can be done only with a piece in hand. If already AACR2, modify to reflect the application of the appropriate rule or rule interpretation.

Record consolidation must not result in the loss of cataloging information. CONSER catalogers should evaluate data elements appearing in the superseded record but not appearing in the selected record and, if necessary, add or suggest that those data elements be added to the selected record. The amount of editing to be done on the retained record is determined by the available information in hand and/or issue consulted.
