Welcome to the revised version of the Canadian website for the MARC 21 formats. Library and Archives Canada (LAC) has developed this site for the convenience of the Canadian library community.
The full French MARC 21 bibliographic and authority formats are now available from this website. Each field is available as a separate pdf file. The full MARC 21 formats in English are available from the Library of Congress web site where it is possible to print directly from the description of each field. It is planned to upgrade the concise French MARC 21 holdings format to the full format in the coming months. This site also includes code lists and other documentation in English and French, with links to corresponding documentation on the Library of Congress website.
The MARC 21 formats are prepared by the Network Development and MARC Standards Office, Library of Congress, in cooperation with Content Management, Library and Archives Canada and Bibliographic Standards and Systems, British Library. Library and Archives Canada is responsible for translating and publishing the French formats.
MARC 21 supersedes the 1994 edition of Canadian MARC Communication Formats and its updates published between 1994 and 1998. Update number six of the bibliographic format contained the changes to CAN/MARC required to align with USMARC. With this update, the specifications contained in the CAN/MARC and USMARC formats were identical. The 1994 edition superseded the 1988 edition and its seven updates issued between 1988 and 1991. The 1988 edition of the bibliographic format was produced by amalgamating separately issued CAN/MARC formats for monographs and serials.
Changes to the MARC 21 formats are based upon proposals considered by the MARC Advisory Committee, the Canadian Committee on MARC (CCM) and by the Book Industry Communications/Bibliographic Standards Technical Subgroup (BIC/BSTS).
Thank you for your continued patience while this site is in transition.
