Service description

ISSN identifies continuously published publications. The Finnish national ISSN Agency is responsible for providing the identifiers in Finland and sends the information about publications that have received an ISSN to the ISSN Portal database.

Identifiers as a part of metadata serve the publishing industry and library sector in their entirety and support identification, processing and availability of publications. The identifiers are used, for example, in publishing industry's ordering and distribution systems to speed up the identification of publications as well as international and domestic joint catalogues, bibliographies, library lending systems and information retrieval. ISSN is inseparable with the name of the publication; if the name of the publication changes, the identifier must also be changed. A separate ISSN is given to various forms of publication.
