TECHNICAL NOTICE (January 10, 2006)
Additions to the MARC Code Lists for Relators, Sources, Description
Conventions
Network Development and MARC Standards Office
Library of Congress
The codes listed below have been recently approved for use in MARC 21 records.
The codes will be added to the online MARC Code Lists for Relators, Sources,
Description Conventions.
The codes should not be used in exchange records until after March 10, 2006.
This 60-day waiting period is required to provide MARC 21 implementers time
to include newly defined codes in any validation tables they may apply to the
MARC fields where the codes are used.
- MARC Term, Name, Title Sources & Other Sources
These codes are for use in subfield $2 in Bibliographic and Community Information
records in fields 600-651 and 655 and in subfield $2 in Authority records
in fields 700-788. Although some of these codes are represented by second
indicator values in 6XX fields in the Bibliographic format and in 7XX fields
in the Authority format, they may be used in situations where the second
indicator is not adequate and/or appropriate to identify the source. An
example is in non-MARC records where the MARC source code list is used,
e.g. the MODS authority
attribute.
