Henriette Avram Develops the MARC Cataloguing Standard

From 1965 to 1968 programmer and systems analyst Henriette Avram completed the Library of Congress MARC (Machine Readable Cataloging) Pilot Project, creating the foundation for the national and international data standard for bibliographic and holdings information in libraries.

The MARC standards consist of the MARC formats, which are standards for the representation and communication of bibliographic and related information in machine-readable form, and related documentation.... Its data elements make up the foundation of most library catalogs.
