080 Universal Decimal Classification Number (NR) (Variable Data Field)
Field definition and scope:
Field 080 contains a Universal Decimal Classification (UDC) number. The Universal Decimal Classification was developed from the Dewey Decimal Classification (DDC) scheme beginning in 1895. In the intervening years, the two systems have become very different in arrangement and philosophy. The UDC may be distinguished from the DDC by its extensive expansions, especially in classes 5 and 6 (science and technology), and by its use of various symbols in addition to Arabic numbers and a single decimal point.
Field 080 is NOT repeatable.
