LCSH stands for Library of Congress Subject Headings.

• A. Library of Congress Subject Headings
• B. Library of Congress Classification
• C. MAchine-Readable Cataloging
• D. Online Public Access Catalog

Answer: (A)

LCSH refers to the system of standardized subject terms used to describe the topics of library resources. These subject headings help catalogs group together works on the same topics so you can find related materials even if different authors use different words. The term stands for Library of Congress Subject Headings, a controlled vocabulary used by many libraries.

The other options point to different library concepts: Library of Congress Classification is the shelving scheme that organizes books by topics in a hierarchical call-number system; MAchine-Readable Cataloging represents the MARC standard for encoding bibliographic data for machines; an Online Public Access Catalog is simply the searchable interface you use to reach a library’s catalog.
