What is the purpose of an ISSN?

The purpose of an International Standard Serial Number (ISSN) is to uniquely identify a specific publication across different formats, which is essential for efficient management and access to serial publications such as journals and periodicals. Each ISSN is a unique eight-digit number that helps in the cataloging and listing of serials in databases, libraries, and indexes, allowing users to find precise information about a publication regardless of its physical format or medium.

The identification capability of an ISSN is particularly important for publishers, librarians, and researchers, as it streamlines the process of citation, retrieval, and citation management. This means that whether a publication exists in print, online, or in any other format, the ISSN remains a consistent identifier that facilitates the recognition and distinction of the publication from others in different formats or editions. By establishing a standardized numbering system, the ISSN enhances the accessibility and discoverability of serial publications within the vast information landscape.
