Quick Summary

The International Serials Data System (ISDS) is responsible for assigning International Standard Serial Numbers (ISSN) to serial publications. An ISSN is an eight-digit number that uniquely identifies a serial publication, similar to how an ISBN identifies a book. This number is crucial for librarians, publishers, and subscription services for administrative tasks, ordering, and inventory control. The ISSN system was developed by the International Organization for Standardization, with guidelines for new assignments and title changes provided by the ISDS. The ISDS, located in Paris, also makes comprehensive ISSN information available.1
