An example of a subject authority heading used in cataloging is

• A. Dewey Decimal Classification
• B. Bibliographic Description
• C. MARC Record
• D. Library of Congress Subject Heading

Answer: (D)

Subject authority headings are standardized topic names used in cataloging so different works on the same topic can be found under a single, consistent heading. The Library of Congress Subject Heading is a prime example of this practice because it’s an official, controlled list of subject terms used to label items for precise subject access. Dewey Decimal Classification, while also a library access tool, is a classification scheme that organizes materials by topic for shelf placement and browsing, not a controlled heading for a specific topic in the catalog. MARC records are the machine-readable format for catalog data and can include subject headings, but they are not the headings themselves. Bibliographic description refers to the details that describe a resource (title, author, publication info) rather than the controlled subject term used for access.
