An ISBN is a special number used to identify books. It stands for International Standard Book Number. This number is meant to be unique for every single book.

This means no two different books should share the same code. Publishers buy or receive these numbers from the International ISBN Agency. It is very important because it helps people find the exact book they want. An ISBN cannot be used for just any title or work. Each version of a book needs its very own number.

For example, a hardcover book needs one code. A paperback version needs a different code. An e-book also needs its own unique number. However, a simple reprint of a book uses the same number.

How these numbers work depends on when they were made. Before 2007, the ISBN was ten digits long. Since January 1, 2007, the ISBN is thirteen digits long.

A thirteen-digit ISBN is made of several different parts. It starts with a prefix, which is usually 978 or 979. Next is the registration group, which shows a country or language. Then comes the registrant element for the publisher. After that is the publication element for the specific book. Finally, there is a check digit at the very end. This last number helps make sure the whole code is correct.

The history of these numbers began many years ago. In 1965, a British bookshop called WHSmith planned a numbering system. They hired a professor named Gordon Foster to help. In 1967, David Whitaker helped create the ISBN format in the United Kingdom. He is often called the "Father of the ISBN." Later, Emery Koltay worked on the format in the United States in 1968. The International Organization for Standardization published the 10-digit format in 1970. This became the international standard known as ISO 2108.

Different countries use these numbers in different ways. The way they are given out depends on the country. Some countries have very large publishing industries. In 2020, the United States was the biggest user of ISBNs. It had 3.9 million registered ISBNs that year.

South Korea was next with 329,582 registrations. Germany, China, the UK, and Indonesia also used many ISBNs. In the United States, there have been over 39 million lifetime registrations.

You can think of an ISBN like a digital fingerprint for a book. Just as your fingerprint is unique to you, an ISBN is unique to a book version.

Other things have special numbers too. Magazines and newspapers use a code called an ISSN. Musical scores use a code called an ISMN. Even some mobile games in China use ISBNs now. These numbers help keep the world of reading organized and easy to search.
