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).

“In comparison to the French Revolution, the American Revolution has come to seem a parochial and rather dull event. This, despite the fact that the American Revolution was successful—realizing the purposes of the revolutionaries and establishing a durable political regime—while the French Revolution was a resounding failure, devouring its own children and leading to an imperial despotism, followed by an eventual restoration of the monarchy.”
—Irving Kristol (b. 1920)
“Envy and jealousy are the private parts of the human soul. Perhaps the comparison can be extended.”
—Friedrich Nietzsche (1844–1900)
