ISSN Agency
An ISSN agency is an organization responsible for assigning and managing International Standard Serial Numbers (ISSNs) to serial publications such as journals, magazines, and periodicals. The main ISSN agency is the ISSN International Centre, which oversees a network of ISSN National Centers around the world. These national centers handle the registration process for publications in their respective countries. For example, in the United States, the Library of Congress acts as the ISSN National Center, while in the UK, it's managed by the British Library. These agencies ensure proper identification, cataloging, and indexing of serials across both print and online formats.
