What does ISSN stand for?

ISSN stands for International Standard Serial Number. It is a unique eight-digit number assigned to serial publications, such as magazines and journals, to provide a standardized way to identify and track them globally. This identification system facilitates the cataloging, distribution, and management of serials in libraries and other information repositories. The ISSN helps distinguish between different publications that may have similar titles, ensuring accurate retrieval and reference in academic and professional settings.

The other options do not accurately represent the established definition of ISSN and do not serve the same purpose. The International Standard Serial Number system plays an essential role in libraries, publishing, and information science, which underscores the importance of understanding its correct definition and application.
