Editing MARC standards (section)

==History==
Working with the [[Library of Congress]], American computer scientist [[Henriette Avram]] developed MARC between 1965 and 1968, making it possible to create records that could be read by computers and shared between libraries.<ref>{{cite web|last=Schudel|first=Matt|title=Henriette Avram, 'Mother of MARC,' Dies|url=https://www.loc.gov/loc/lcib/0605/avram.html|publisher=Library of Congress|access-date=June 22, 2013}}</ref><ref>{{cite journal|first=Sally H.|last=McCallum|title=MARC: Keystone for Library Automation|journal=IEEE Annals of the History of Computing|volume=24|issue=2 |date=2002|pages= 34–49|doi=10.1109/MAHC.2002.1010068}}</ref>  By 1971, MARC formats had become the US national standard for dissemination of [[Bibliographic database|bibliographic data]]. Two years later, they became the [[international standard]]. There are several versions of MARC in use around the world, the most predominant being [[MARC 21]], created in 1999 as a result of the harmonization of U.S. and Canadian MARC formats, and UNIMARC. UNIMARC is maintained by the Permanent UNIMARC Committee of the [[International Federation of Library Associations and Institutions]] (IFLA), and is widely used in some parts of Europe. 

The MARC 21 family of standards now includes formats for [[authority record]]s, holdings records, [[Library classification|classification schedules]], and community information, in addition to the format for [[bibliographic record]]s.
