Comparison To Other Identifiers
ISSN and ISBN codes are similar in concept, where ISBNs are assigned to individual books. An ISBN might be assigned for particular issues of a periodical, in addition to the ISSN code for the periodical as a whole. An ISSN, unlike the ISBN code, is an anonymous identifier associated with a periodical title, containing no information as to the publisher or its location. For this reason a new ISSN is assigned to a periodical each time it undergoes a major title change.
Since the ISSN applies to an entire periodical a new identifier, the Serial Item and Contribution Identifier, was built on top of it to allow references to specific volumes, articles, or other identifiable components (like the table of contents).
