Self-Published Books: What is an ISBN number? Do I need one?
What is an ISBN Number?
ISBN stands for International Standard Book Number. An ISBN is
a numeric code that uniquely identifies the book to which it is assigned. ISBN
numbers are usually placed on the lower back cover of a book as well as the
copyright page.
ISBN numbers are the universally accepted format for
identifying books. As such, they are generally a requirement if you plan to sell
your books commercially, especially through traditional channels like
bookstores, distributors, and wholesalers.
The Origin and Format of ISBN Numbers
The ISBN system was developed in the mid 1960's by a large
UK book retailer that wanted to establish a computerized inventory system for its
multitude of book titles. The idea was soon adopted by others in the publishing
industry who also recognized the value of having a standardized identification
system for books. By the early 1970's, the use of ISBN numbers was spreading
around the globe.
Each ISBN uses a long string of numbers to encode information about a book. Prior to 2007, ISBN numbers were 10 digits in length (ISBN-10). The 13-digit ISBN format (ISBN-13) was introduced on January 1, 2007 and has been in use ever since.
A 13-digit ISBN consists of five basic sections with each
section separated by a hyphen...
1. The first part will be "978" or "979" to identify the
data string as a 13-digit ISBN number.
2. The second part identifies the geographic region where
the book's publisher is located (where the book was actually printed is not
coded into the ISBN, only the region where the publisher is located)
3. The third part identifies the particular publisher (if
you are Self-Publishing, that's you!)
4. The fourth part identifies a specific title or an edition/version
of a title
5. The fifth and final part is a check digit, which is derived from a
mathematical formula and used to verify that all the other numbers in the ISBN data
string are correct.
ISBN Numbers Follow Established Guidelines
The International ISBN Agency is located in London, England.
It oversees and regulates 160+ regional and national ISBN agencies throughout
the world.
R. R. Bowker LLC, located in Chatham, New Jersey, is the official
ISBN agency for the United States. Whether an author is Self-Publishing a book
or relying on a publishing service, all ISBN numbers obtained in the U.S. are
issued by Bowker. An initial fee is charged for ISBN numbers but there is never a renewal charge because the numbers don't expire.
It is also important to note that each ISBN identifies one book
title, or one version of that title. This means if a title is
released as a softcover book and a hardcover book, each version will need its
own unique ISBN.
Also, whenever a book comes out as a new edition, each
edition will need its own ISBN. This rule applies even when the same book is
produced as a large print edition or translated into a foreign language. Every variation of the book will need its own ISBN number.
Once an ISBN has been assigned to a specific book, that particular
ISBN number will never be issued again nor should it ever be used for any book
other than the one for which it was originally created.
Do I need an ISBN Number?
Whether or not you need an ISBN number as a Self-Publisher will
largely depend on how you plan to distribute your printed book.
You WILL NOT need an ISBN Number if…
- Your book will be given away free of charge, such as a book created for promotional purposes or as a gift to family or acquaintances.
- You will be the one selling the book directly to end users, such as by in-person contact or through your own website or store.
- Your book will be sold through an online retailer that does not require an ISBN. For example, Amazon will assign its own standard identification number (ASIN) to your book so it can be sold through their website.
- Your book will be used privately by a company or organization, such as a technical manual or handbook.
You WILL need an ISBN Number if…
- Your book will be sold through bookstores or other retail outlets.
- Your book will be sold through a distributor network or wholesaler.
- Your book will be offered by a college or university, such as a textbook or workbook.
- Your book will be made available to libraries.
How do I get an ISBN Number?
Fortunately, the process of obtaining an ISBN number is relatively
simple. You can order directly through Bowker by visiting the isbn.org website.
IMPORTANT: Because ISBN numbers are owned by the publisher
of a book, it is recommended that Self-Publishers purchase these numbers directly. This allows you to retain ownership of the ISBN number and provides the most control over the book, both now and in the future.
