Definition

 Contains the International Standard Serial Number (ISSN). ISSNs consist of eight digits in two groups of four, separated by a hyphen. Use for ISSNs found in New Serial Titles, other Bowker serials publications, or in the issue being cataloged so that the record can be authenticated by the National Serials Data Program.

Note: This field is used for both serials and integrating resources.

Validation

 		 The final character of an ISSN is a calculated check character, either numeric, 0–9, or X. It is used to identify and eliminate typographical errors.

When you validate a record containing field 022, the system checks the ISSN in subfield ‡a to verify that the content and length are correct and that the check character matches the calculated check character.

If there is an error in the ISSN (e.g., the ISSN is too long or too short, lacks a hyphen after the fourth digit, or has an invalid check digit), the system displays an error message and the ISSN remains in subfield ‡a. If you made a typographical error, correct the ISSN and validate the record again. If the error message appears again and you transcribed the ISSN exactly, the ISSN is in error. Put the ISSN in subfield ‡y .

1st indicator

blank character No level specified. The level of international interest is unknown or not specified. Used by all institutions other than the National Serials Data Program (NSDP) and ISSN Canada when recording the ISSN from an issue or from a bibliography.
0 Continuing resource of international interest. Full record registered with the ISSN Network
1 Continuing resource not of international interest. Abbreviated record registered with the ISSN Network

2nd Indicator

‡y Incorrect ISSN

022 0145-0808 ‡z 0361-7106

Prior to 1978, OCLC defined subfield ‡z for both canceled and incorrect ISSNs. Such records may still have incorrect ISSNs in subfield ‡z .

The code for the ISSN Centre that assigned the ISSN. The most commonly used codes are:

0 ISSN International Centre
1 United States
2 United Kingdom
4 Canada
z Other

For the full list of codes, see the ISSN National Centres code list at http://www.issn.org/en/flexinode/table/1.

Printing
  Field 022 subfield ‡a prints as the last note. If a key title ( field 222) is present when you Produce, the key title also prints in the note.

If multiple 022 fields are in a record, the system prints the first 022 field with a valid ISSN.

AACR2 records. The ISSN precedes the key title. The print program supplies ISSN before the number and a space equal-sign space between the ISSN and the key title.
