An ISSN record represents the authority record for a continuing resource title [See also section 4. ISSN record]. An ISSN record has different statuses depending how and when they were created, and for which resource:

• Confirmed records correspond to resources whose publication has been checked by the ISSN Network.

• Provisional records correspond to provisional ISSN that may be assigned to pre-publications; they are liable to become Confirmed records.

• Legacy records were created at the infancy of the ISSN Register; their bibliographic data is incomplete and not up-to-date.

• Cancelled records correspond to cancelled ISSN, e.g. if an ISSN was mistakenly assigned twice, it is then cancelled and a new ISSN is re-assigned.

• Suppressed records correspond to ISSN that were deleted, generally because the resource described is not a continuing resource or has never been published.

• Unreported records correspond to identifiers not yet assigned and that are not (yet) reported to the ISSN International Centre.
