Library of Congress CDS Announcement Revision to MARC Coding in the Authority 682 Field In order to better support automated linking, the Library of Congress is revising the policy on the subfield coding used in the 682 field (Deleted Heading Information) with in cancelled subject heading and genre/form authority records. This revision will affect MARC Distribution Service Subject-Authorities subscribers. Records with the new coding will be distributed no earlier than April 7, 2015. All LCCNs present in the 682 field will now be coded in subfield $0 (Replacement authority control number). This subfield will be repeated if necessary . Each LCCN will be preceded by the Library of Congress' organization code, DLC. Examples: 682 ## $iThis authority record has been deleted because the heading is covered by the subject heading $a [heading] $0 (DLC)shXXXXXXXXXX 682 ## $i This authority record has been deleted because the subject heading is covered by an identical name heading $0 (DLC)n XXXXXXXXXX 682 ## $a This authority record has been deleted because the heading is covered by the subject headings $a [heading] $0 (DLC)shXXXXXXXXXX $i and $a [heading] $0 (DLC)shXXXXXXXXXX This coding revision will affect only those records that are cancelled after April 7, 2015, since it is not possible to revise the coding in records that have already been cancelled.
