The MARC Forum is a moderated electronic discussion forum open to anyone interested in discussing the implementation, maintenance, changes, and development of the MARC 21 formats. It is maintained by the Library of Congress Network Development and MARC Standards Office. The MARC Forum provides the opportunity for members of the information community to participate in discussions related to the formats.
Vendor, network, technical service, automation, and reference staff and researchers are encouraged to participate. While there is a close linkage between MARC 21 as a communications format and the cataloging of materials, the focus of the MARC Forum is on MARC 21 the communications format.
