Announcement on Newer MARC 21 Characters in NACO Records
Plans for implementing some of the newer MARC 21 characters have been agreed to by the NACO nodes (British Library, Library of Congress, National Library of Medicine, OCLC, Inc.). As of Oct. 22, 2007 the following characters will be allowed in records contributed to the LC/NACO Authority File (see the code tables at http://www.loc.gov/marc/specifications/specchartables.html for encoding information):
Opening curly bracket
Closing curly bracket
Lower case script L
Phono copyright mark
Inverted question mark
Inverted exclamation mark
Implementation of a few other newer characters is deferred at this time—separate announcements will be made when they may be used:
Eszett (continue to use “ss” per LCRI 1.0E)
The Library of Congress will work with OCLC, Inc. with regard to identifying and converting existing NACO records using the number sign for the musical sharp, and superscript zero for the degree sign.
Note non-Latin characters may not be used in authority records at this time—a separate announcement will be made when appropriate, no earlier than April 2008.
