GUIDELINES FOR APPLYING CONTENT DESIGNATORS
■ INDICATORS
First Indicator - Level of international interest Whether the continuing resource is of international interest or of local or
ephemeral interest only.
# - No level specified Level of international interest is unknown or not specified. Used by all
institutions other than the ISSN Centers when recording the ISSN from an issue
or from a bibliography.
0 - Continuing resource of international interest Continuing resource is of international interest, thus a full record has been
registered with the ISSN Network. This value is used for all continuing
resources for which individual ISSN Centers receive ISSN requests from
abstracting and indexing services or other ISSN Network centers. Value 0 is
also used for all other continuing resources that are not within the scope
defined for value 1. This value may be input only by the ISSN Centers.
1 - Continuing resource not of international interest Continuing resource is not of international interest, thus an abbreviated
record has been registered with the ISSN Network. Value 1 is used for
continuing resources judged to be of local or ephemeral interest. ISSN Centers
have defined publications of local or ephemeral interest as those in which
interest is likely to be limited to a certain geographic area, e.g., local
newspapers, or certain span of time, e.g., calendars of events. In case of
doubt, value 0 is used. This value may only be input by the ISSN Centers.
Second Indicator - Undefined Undefined and contains a blank (#).
■ SUBFIELD CODES
$a - International Standard Serial Number Valid ISSN for the continuing resource. ISSN may be generated for
display.
$l - ISSN-L ISSN that links together various media versions of a continuing resource.
ISSN-L may be generated for display.

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).
Punctuation - Field 022 does not end with a period.
