5. What is an ISBN, and why do you need it?

Welcome to the fifth post in a series of articles on writing, publishing and marketing your next book.

Here are the other blogs in the series

ISBN means international standard book number and is something you are quite familiar with. If you look at the back of most books, you will find a string of 13-digit numbers (for books published before 2007, it is 10), that is the ISBN.

Basically, it is a product identifier that is used by publishers, internet retailers, libraries, bookshops and other supply chain participants for ordering, listing, sales records, and stock control purposes. It identifies the country that your book is from, the publisher, and even the book itself gets an identity.

You don’t necessarily have to get an ISBN, but if it is part of your plans to sell your book through a distributor, a book store, an online store or if you plan to have your book in a library, then you will need to get one. It makes locating and identifying your book easy for them.

Getting an ISBN is an important step in planning ahead for your book and it is highly advised and encouraged by us. Whether you want to purchase your own ISBN or publish under Composio Publishing’s ISBN, we allow you to do either or on our platform.
