FIELD DEFINITION AND SCOPE

copied from field 022 of a MARC 21 bibliographic record for a continuing resource.
The inclusion of this field in the established heading record for a series which
identifies an occasionally-analyzed issue of a continuing resource provides a machine
link within a system between the authority record for the series and a bibliographic
record in which the heading is used as a series added entry. The subfields for this
field are defined for consistency with field 022 in the MARC 21 Format for
Bibliographic Data.
International Standard Book Number (ISBN) associated with a multipart item that is
cataloged as a set is contained in field 020 (International Standard Book Number).

INPUT CONVENTIONS
ISSN Structure - ISSN is an agency-assigned data element. ISSNs are assigned to continuing resource
publications by national centers under the auspices of the ISSN Network. An ISSN
consists of eight digits comprising two groups of four digits each, separated by a
hyphen. The eighth digit is a check digit used as a computer validity check; it consists
of a number between 0 and 9 or an uppercase X (for the arabic numeral 10). A description
of the ISSN structure and the procedure for validation of the ISSN by calculating the
check digit is in International Standard Serial Numbering (ISSN) (ISO
3297).
