Some students are under the mistaken impression that the ISBN is used only to classify textbooks. However, this number is used in selling all kinds of books. People looking to get a price quote on a book or get more information about it can visit an ISBN database or any other book search website and look up a book by the ISBN – this interaction is known as ISBN search or ISBN lookup. ISBN search sites provide details of a book, including title, author, publisher, etc. If a person is interested in purchasing a book, the ISBN helps to find it.

In the publishing industry, each book is given a unique identifier called the ISBN (International Standard Book Number). This code acts as a digital fingerprint, simplifying cataloging, distribution, and sales tracking. The ISBN system assigns meaning to the numbers, providing a range of information about the book.
As the publishing industry progresses, so does the ISBN system. It has transitioned from a 10-digit to a 13-digit format and now includes a 979 prefix to accommodate the diverse range of published materials. This blog post will explore what an ISBN is, how it came about, and its role in simplifying the complex world of books and publications.

An ISBN is an International Standard Book Number, found on every published book and contains a series of unique numbers.
“An ISBN is assigned to each separate edition and variation (except reprintings) of a publication.” Wikipedia
The ISBN is usually found on the back of a book and is accompanied by a barcode. So, why do you need to know the difference between ISBN 10 and ISBN 13?
