Field Definition and Scope

This field contains the record identifier of a record that has been merged into the current one for deduplication.

Application of Content Designators

Indicators

both indicators are undefined and thus left blank

Subfields

$z Obsolete record identifer (M;NR)
CERL Thesaurus record identifier of a deleted record, which content was merged into the current record.

Input Conventions

This field is created automatically when two records are merged (either in an offline updating process or by using the WinADH database client). A field 035 must by no means be deleted from a record, in order to ensure that all record identifiers ever assigned to a CERL Thesaurus record are kept valid.

This field is used for CERL Thesaurus identifiers only. Identifiers from other systems should be given in the respective field 801 Originating Source (O;R).
