Machine-Readable Cataloging (MARC)
An international standard digital format for the description of bibliographic items developed by the Library of Congress during the 1960s to facilitate the creation and dissemination of computerized cataloging from library to library within the same country and between countries. By 1971, the MARC format had become the national standard for dissemination of bibliographic data and by 1973, an international standard.

MARC 21
The version of Machine Readable Cataloging that superseded USMARC in 1999 with the harmonization of U.S. and Canadian MARC formats. MARC 21 is supported by OCLC and is the current official MARC standard in the United States, Great Britain, Canada, Australia, and numerous other countries. Click here to learn more about MARC 21 development and here to browse the MARC 21 Concise Formats.

Universal Machine-Readable Cataloging (UNIMARC)The most comprehensive version of the MARC format for cataloging bibliographic items, UNIMARC was first published in 1977 and is currently developed under the sponsorship of the IFLAUniversal Bibliographic Control and International MARC Core Activity (UBCIM) program to facilitate the international exchange of bibliographic records between national bibliographicagencies. See the UNIMARC Manual: Bibliographic Format 1994 (IFLA) and UNIMARC to MARC 21 Conversion Specifications (Library of Congress)

USMARC
A set of standards for the representation and communication of bibliographic data and related information in machine-readable format, originally developed and maintained for use in the United States and superseded in 1999 by MARC 21 with the harmonization of U.S. and Canadian MARC formats. USMARC governed three aspects of bibliographic description: (1) record structure, (2) content designation, and (3) the actual data content of the record. The Library of Congress is advised on the maintenance and development of MARC standards by the U.S. MARC Advisory Committee, representing various user communities in North America
