Topical term used as an index term that supplements terms derived from data in the MARC classification record. The term may be referred to in the classification number and caption in field 153 (Classification Number).

May be used to link a classification number with a related controlled subject heading. Topical index terms may consist of general subject terms including names of events or objects. The 750 field provides access to classification numbers according to generally accepted thesaurus-building rules (e.g., Library of Congress Subject Headings, (LCSH), Medical Subject Headings (MeSH)). The values in the second indicator position or in the data in subfield $2 (Source of heading or term) identify the subject heading system or thesaurus used by an institution to formulate the topical index term. To be included in this field, a topical index term must match the controlled heading, including any subdivisions. Index terms not controlled by a thesaurus are contained in field 753 (Index Term-Uncontrolled).


Guidelines for applying subfield $i (Explanatory text) and subfield $0 (Record control number) and examples of field 750 are provided in this section. Guidelines for applying the remaining content designators and input conventions are provided in the MARC 21 Format for Bibliographic Data: field 650 (Subject Added Entry-Topical Term).
