A cataloger may need to indicate a different mode of issuance than that originally identified for a bibliographic resource. Such a situation can occur for two reasons:
- A bibliographic resource can change its mode of issuance (an electronic serial can become an electronic integrating resource); and,
- The mode of issuance can be incorrectly identified at the beginning of processing a bibliographic resource in a library.
The primary basis for determining action is the presence/absence of an LCCN. If the record has an LCCN, it has been received, is maintained, and, depending upon the processing status of the bibliographic resource, is distributed by CDS. The accompanying table shows actions required when a bibliographic resource changes its mode of issuance. Much of the complexity in the table is due to requirements that records distributed in one of the Cataloging Distribution Service's product lines cannot be re-distributed in another product line until it has been deleted from the original product line (i.e., must be deleted then re-added).
All possible conditions of change have been included in the table, although it is likely that several of them may not occur.
