Definition |
The entry number for an item found in a national bibliography outside the United States. An item may have multiple numbers from a single national bibliography or may have multiple numbers from more than one national bibliography. Multiple numbers are recorded in separate 015 fields. If LC derives its cataloging data from a national bibliography, LC cataloging copy includes the national bibliography number. Each number may have a one-to-four letters designating the country, a space, an indication of the year, and a serial number. If the number is a bibliographic record control number used by a national library, rather than an official national bibliography number, use field 016. If the number is a PL 480 or LACAP number, use field 025. If the number is for materials acquired in Africa, which have accession numbers similar in form to national bibliography numbers, use field 025. |
