INDICATORS

SUBFIELD CODES

$a - Source citation

Citation for a published work or a description of any source or action that provided information about the heading (e.g., a telephone call to a publisher). The citation includes enough information to identify the work, such as the title and imprint date. When a work has a non-distinctive title (e.g., a generic term), the citation may begin with the name of the author. When the author is the same as the 1XX heading, one of the following may be used in the citation: His, Her, Author's (gender unknown), or Its (not a personal name). When a 100 heading is used for more than one person (008/32, Undifferentiated personal name, code b), subfield $a may contain a descriptive term for an author enclosed within brackets (e.g., [Author of Ireland]).
