The ISSN or International Standard Serial Number identifies a serial publication. It does not identify a particular issue or a particular article in an issue. DOIs identify particular articles. Normally an ISSN is not part of a citation to a particular article. An ISSN is used to identify the serial, i.e., the journal or periodical. Only use an ISSN in a citation for a particular article if the journal is relatively unknown and the ISSN is provided for verification of the existence of the journal. An ISSN is used when the reference is to the journal as a whole.
Template:ISSN can be used to insert and format an International Standard Serial Number (ISSN) for a publication in article, such as inside a reference citation, or at the article about a notable publication.
