What Is the Difference Between an ISSN and an ISBN?

An ISSN (International Standard Serial Number) and an ISBN (International Standard Book Number) serve different purposes in identifying publications. ISSNs are assigned to serial publications, while ISBNs are used for books and monographs.

Key Differences Between ISSN and ISBN:

ISSN (International Standard Serial Number)

• Used for serial publications such as journals, magazines, newspapers, and periodicals.
• Composed of eight digits (e.g., 1234-5678).
• Identifies an entire publication series, not individual issues or volumes.
• Managed by the ISSN International Centre and national ISSN agencies.

ISBN (International Standard Book Number)

• Used for books, monographs, and standalone publications.
• Composed of 13 digits (e.g., 978-3-16-148410-0).
• Assigned to each edition and format of a book (e.g., hardcover, paperback, e-book).
• Managed by ISBN agencies in each country.

Can a Journal Have Both an ISSN and an ISBN?

A journal itself only requires an ISSN, but if a journal publishes a special edition, conference proceedings, or a book-style volume, that specific issue may require an ISBN.

Should a Book Series Use an ISSN or ISBN?

• If the series consists of standalone books, each book should have its own ISBN.
• If the series is a continuing publication with a consistent title, an ISSN may be more appropriate.

How to Obtain an ISSN or ISBN?

• ISSNs can be obtained from the ISSN International Centre or national ISSN agencies.
• ISBNs are issued by national ISBN agencies in each country.
