For those in the publishing sector, managing unique identifiers like the International Standard Serial Numbers (ISSN) and International Standard Book Numbers (ISBN) is crucial. Although both numbers serve to uniquely identify a publication, they are not the same and serve different types of publications. In this blog, we’ll break down the essential differences between ISSN and ISBN to assist publishers in comprehending their specific roles and applications.

What is an ISSN?

An ISSN is a unique number used to identify serial publications such as journals, magazines, newspapers, and periodicals available online. This identifier is crucial for library cataloging and managing serial publications in databases. The ISSN consists of eight digits, split into two groups of four with a hyphen in between. If you need an ISSN, you can obtain one from the International ISSN Centre website by finding your local ISSN Agency.

The ISSN barcode (in EAN-13 format) is generated by adding "977" to the first seven digits of the ISSN, then appending a two-digit price code (typically "00"), and recalculating the check digit (the 13th digit). Often, a two-digit add-on barcode indicates the issue number (e.g., 01 for issue 1).

What is an ISBN?

An ISBN is a 13-digit identifier designated for books and book-like products such as e-books, audiobooks, and microforms. This number is essential for tracking and managing book distribution. If you don't have an ISBN, you can obtain one by visiting the International ISBN Agency website to find your local ISBN Agency.

The ISBN barcode uses the EAN-13 format to encode the 13-digit ISBN. The ISBN number is generally printed above the barcode.

The primary difference between ISSN and ISBN lies in the type of publications they are assigned to. While ISSN applies to serial publications issued periodically, ISBN is reserved for books and similar products. Furthermore, ISSN is assigned to the entire publication series, whereas ISBNs can be issued for different formats or editions of the same book.

In Summary

Publishers should ensure they correctly allocate ISSNs and ISBNs to avoid confusion and maintain proper records.

In conclusion, ISSN and ISBN are vital for publishers to uniquely identify and categorise their publications. Grasping the distinctions between ISSN and ISBN is crucial for effective management and promotion within the publishing world. By following the guidelines outlined here, publishers can accurately assign ISSNs and ISBNs, enhancing their publications' visibility and accessibility to readers and other stakeholders.
