Field definition and scope:

Field 730 contains a uniform title used as an index term that supplements terms derived in the MARC record.  The uniform title may be referred to in the classification number and caption in field 153 (Classification Number).

The field may be used to link a classification number with a related controlled uniform title heading.  The values in the second indicator position or the data in subfield $2 (Source of heading or term) identify the subject heading system or thesaurus used by an institution to formulate the uniform title index term.  Terms not controlled by a thesaurus or authority file are contained in field 753 (Index Term - Uncontrolled).

Field 730 is repeatable.

Guidelines for applying content designators:

 Field 730 parallels the 630 Subject Added Entry field in the bibliographic format.  The indicators and subfield codes below were created from the information in field 630.  Examples of field 730 are provided in this section.  Guidelines for the input conventions and the source for the content designators are in MARC 21 Format for Bibliographic Data:  X30 (Uniform Titles - General Information) and 630 (Subject Added Entry - Uniform Title).
