DCM Z1: 022 International Standard Serial Number
LC series practice: As of June 1, 2006, LC does not create or update SARs.
PCC series practice: Transcription of the series statement is mandatory if applicable. Searching for series authority records, tracing the series, and the creation and maintenance of series authority records are optional.
Record the ISSN whenever it is available from the item in hand, from analytic bibliographic records, or from the collected set bibliographic record for the series; otherwise, recording the ISSN is optional.
When it is known there are separate ISSN assigned to different formats of a series represented by a single SAR, prefer to record in 022 subfield $a the ISSN that is the linking ISSN (ISSN-L) for the different formats. Identify ISSN for specific formats in separate 667 fields, following this pattern:
667 ## $a Print version: ISSN XXXX-YYYY
667 ## $a Online version: ISSN YYYY-ZZZZ
When the title of a publication has changed, confirm that an ISSN appearing on the publication belongs to the new title and not to the earlier title.
An incorrect ISSN can be given in a 667 field (e.g., "ISSN 1122-3344 is not a valid ISSN for this publication").
