MARC Standards
MARC (MAchine-Readable Cataloging) standards are digital formats for the description of bibliographic items developed by the Library of Congress during the 1960s to facilitate the creation and dissemination of cataloging between libraries. By 1971, MARC formats had become the national standard for dissemination of bibliographic data and the international standard by 1973. 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, widely used in Europe. The MARC 21 family of standards now includes formats for authority records, holdings records, classification schedules, and community information, in addition to the format for bibliographic records.

“Imagination has seized power.
[L’imagination prend le pouvoir.]”
—Graffito. Paris ‘68, ch. 2, Marc Rohan (1988)
“There are ... two minimum conditions necessary and sufficient for the existence of a legal system. On the one hand those rules of behavior which are valid according to the system’s ultimate criteria of validity must be generally obeyed, and on the other hand, its rules of recognition specifying the criteria of legal validity and its rules of change and adjudication must be effectively accepted as common public standards of official behavior by its officials.”
—H.L.A. (Herbert Lionel Adolphus)
