THE FINNISH ISSN CENTRE IS CLOSED 23.12.-30.12.2016.
The ISSN identifies continuing resources. The Finnish ISSN Agency is responsible for assigning the identifiers in Finland and for sending the information on publications which have been assigned ISSN identifiers to the ISSN Portal database.
The ISSN is tied to the title of the publication. If the title changes, the identifier must also be changed. Information on publications which have been assigned ISSN identifiers will be entered both into the national Fennica database and the international ISSN Portal.
