Which U.S. institution catalogs published works?

• A. Library of Congress
• B. National Library
• C. Public Library
• D. Archives

Answer: (A)

Cataloging published works is a function of a national library, which collects and organizes the literature produced in a country so that libraries everywhere can access standardized bibliographic records. In the United States, the institution that serves as this national library is the Library of Congress. It not only preserves a vast corpus of published materials but also creates and maintains the bibliographic records—using systems like Library of Congress Cataloging in Publication data, the LC Classification, and LCSH—that libraries rely on to catalog and retrieve items. This centralized cataloging framework helps libraries across the country and beyond to locate resources efficiently.

A public library focuses on serving its local community and catalogs its own holdings, not the entire spectrum of published works. Archives specialize in preserving and providing access to historical records, manuscripts, and original source materials rather than the broad cataloging of current publications.
