What is an International Standard Serial Number (ISSN)?
The International Standard Serial Number (ISSN) is a standard 8-digit number that uniquely identifies any serial publication independently of place of publication, language, frequency, or medium. ISSNs are in no way related to Library of Congress Control Numbers and are only related to CIP data to the extent that a series statement in the CIP data will include the ISSN if the ISSN associated with the series appears in the published book and the publisher has provided this information when requesting the CIP data.
