SUBFIELDS

675a Number

If there are more UDC groups entered in the record, the record is classified under the first group in standard bibliographies.

675c UDC access*

In this subfield, enter the UDC number intended for content searching and sorting in the COBIB shared database and local databases. The subfield entry is supported by a global code list that is uniform for all types of material (see Appendix G). Subfield is mandatory.

An identification of the edition from which the number in subfield a is taken.

675z Language of edition

NOTES ON FIELD CONTENTS

In subfield a, enter the number from the UDC schedules used by the agency preparing the record. UDC is produced in various language versions each of which is revised from time to time and published as a new edition. Each published edition of UDC is derived from the UDCMRF (Universal Decimal Classification Master Reference File).

In some libraries, the subject cataloguing is preceded by descriptive cataloguing, which allows the use of the temporary "fik" code in subfield 675c. When subject cataloguing, the fictive code must be replaced by a corresponding UDC access number.

Until 1992, subfields 675x and 675y were also used for the needs of the Bulletin Scientifique publication display.
