International Standard Serial Number facts for kids

An International Standard Serial Number (ISSN) is a special eight-digit number. It helps to identify magazines, newspapers, and other publications that come out regularly. Think of it like a unique ID card for these publications.

What is an ISSN?

An ISSN is a unique code given to publications that are released over time. These are called "serials" or "periodicals." This includes things like daily newspapers, weekly magazines, and yearly journals.

The ISSN helps to tell one publication apart from another. Even if two magazines have similar names, their ISSNs will be different. This makes it easy to find and organize them.

Why are ISSNs important?

ISSN numbers are very useful for many reasons. They help libraries keep track of their collections. Publishers use them to manage their different titles.

• Finding publications: An ISSN makes it simple to search for a specific magazine or journal.
• Ordering and selling: Bookstores and distributors use ISSNs to order and sell publications correctly.
• Identifying different versions: If a magazine comes out in print and also online, each version might have its own ISSN. This helps to tell them apart.

How does an ISSN work?

An ISSN is made up of eight numbers. These numbers are usually separated by a hyphen, like 1234-5678. The last digit is a special "check digit." This digit helps to make sure the number is correct.

The check digit is calculated using a special math formula. If someone types an ISSN incorrectly, the check digit often helps to spot the mistake. This makes the system very reliable.

Who created the ISSN system?

The ISSN system was first created in 1975. It was developed by the International Organization for Standardization (ISO). The ISO is a group that sets standards for many things around the world.

The specific standard for ISSN is called ISO 3297. A special committee within ISO, called TC 46/SC 9, is in charge of keeping this standard updated. They make sure the ISSN system works well for everyone.

Where can you find an ISSN?

You can often find the ISSN printed on the publication itself. For a magazine, it might be on the cover, inside the front page, or on the copyright page.

For online publications, the ISSN is usually found on the website. It might be on the "About Us" page or in the footer of the website. Libraries also list the ISSN for publications in their catalogs.
