Henriette Avram

Henriette Davidson Avram was a computer programmer and systems analyst who developed the MARC format, the international data standard for bibliographic and holdings information in libraries. Avram's development of the MARC format in the late 1960s and early 1970s, at the Library of Congress had a revolutionizing effect on the practice of librarianship, making possible the automation of many library functions and the sharing of bibliographic information electronically between libraries using pre-existing cataloging standards.
