What is an ISBN
ISBN stands for International Standard Book Number, each ISBN contains 13 digits about your format, language and publisher. This enables your book to be entered into a database which is available to lending libraries, bookstores and wholesalers. One of the important basics of publishing your book.
All ISBNs are created with a barcode so that each book can be easily identified the world over. Usually found on the back cover of a book, and also on the copyright page of the book.
Do I Need to Buy an ISBN for My Book?
If you're selling your book through your own platform you don't necessarily need an ISBN number.
An ISBN is required if you're selling through a major bookstore, such as Amazon. Kindle Direct Publishing, which is Amazon's print-on-demand service, will automatically give you an ISBN barcode for free.
Other self-publishing companies will provide you with an ISBN to generate a barcode, usually this will be incorporated within your publishing package or at a small cost. Like Kindle Direct Publishing, they become they publisher of your work.
When you print through a large publisher such as Amazon you don't need to deal with the registration and data management of your book.
Hardcover books require a separate ISBN number than the paperback version, this is so the book can be easily identified as a hardcover in directories, catalogues, and databases.
Do I Need an ISBN for an Ebook?
No you don't need to worry about any kind of code for an eBook. Kindle Direct Publishing has its own system known as the ASIN (Amazon Standard Identification Number). When you'll be given this number for free.
Other retailers such as Barnes and Noble and Apple's iBook, all like you to have an ISBN, but don't automatically require it.
You don't need to waste your money buying an ISBN, but there's nothing stopping you if you want to go ahead and purchase one.
What you mustn't do is use the same ISBN number for different books you have in print. Every format you have published requires a different ISBN code. This means every paperback book you have published must have a separate ISBN number, even if it's the same title.
