You can access the Fennica database to see whether your publication already has an ISSN:
A new ISSN is required if
- The resource title has been changed
- The resource is being issued in another language in its entirety
- The resource is being issued in another format, e.g., online or on CD-ROM.
If the publication of a continuing resources ends, this must be reported to the ISSN Agency so that the information of the publication may be updated into the relevant databases.
