Here is the complete library of MARC documentation -- everything you need. Library of Congress MARC publications set the standard for MARC cataloging documentation in library automation, forming the backbone of automated library systems, networks, and bibliographical utilities. The Library of Congress, the British Library, and the National Library of Canada harmonized the USMARC, UKMARC, and CAN/MARC formats, and joined their MARC documentation to form MARC 21. Available in Cataloger's Desktop and free online on the Library's MARC web site.
