Authority 016 szerkesztése (szakasz)

== STRUCTURE OF THE LAC CONTROL NUMBER ==


:With the redefinition of field 016 in 1997, any national bibliographic agency can record its control number in this field. Although the structure of numbers would vary from agency to agency, extensive use of field 016 has been made by Library and Archives Canada. Their control number structure is given below.

:Language code (character position 9) identifies with a code “E” (English) or “F” (French), a bilingual heading for which two separate authority records, one in English, the other in French, are produced.

:LAC control number is carried in fields 016 (subfield $a) and 001 (Control Number) in records distributed by LAC’s MARC Records Distribution Service.
