Publishers in the UK frequently encounter the need to allocate identification numbers to their works, such as International Standard Serial Numbers (ISSN) and International Standard Book Numbers (ISBN). While both identifiers serve to uniquely label a publication, their differences are significant and must be understood. This guide delves into the fundamental contrasts between ISSN and ISBN to aid publishers in grasping their respective roles and uses.

What is an ISSN?

An ISSN is a unique identification number assigned to serial publications, including journals, magazines, newspapers, and digital releases that appear on a regular schedule. It is pivotal for cataloguing and organizing serials in libraries and databases. ISSN numbers are formatted as eight digits split into two groups of four, separated by a hyphen. If you don't have an ISSN number, you can obtain one by visiting the International ISSN centre website and finding your local ISSN Agency.

An ISSN can be transformed into an ISSN barcode (using the EAN-13 format) by placing "977" before the first seven digits of the ISSN, followed by a 2-digit price code (usually "00"), and recalculating the check digit (the 13th digit). Occasionally, an additional 2-digit barcode is added at the end to denote the issue number (e.g. 01 = issue 1).

What is an ISBN?

An ISBN is a 13-digit identifier exclusively allocated to books and book-like products, such as e-books, audiobooks, and microforms. ISBNs play a crucial role in tracking and managing the distribution of books in the marketplace. If you don't have an ISBN, you can get one by visiting the International ISBN Agency website and finding your local ISBN Agency.

An ISBN barcode is an EAN-13 format barcode that incorporates the 13-digit ISBN. Typically, the ISBN is printed above the barcode.

One major difference between ISSN and ISBN is the type of publication they refer to. ISSN is intended for serial publications that are released periodically, whereas ISBN is specific to books and similar products. Moreover, ISSN usually applies to the publication as a whole, whereas ISBN can be assigned to various formats or editions of a single book.

In Summary

It is crucial for publishers to assign ISSN and ISBN accurately to their publications to prevent confusion and maintain precise records. 

 In conclusion, both ISSN and ISBN are vital for uniquely identifying and categorising publications. Understanding their differences is essential for publishers aiming to manage and market their works effectively. By adhering to the guidelines in this guide, publishers can ensure correct assignment of ISSN and ISBN, thus enhancing visibility and accessibility to readers and stakeholders.
