International Book Number FAQ
I hope the answers to the most frequently asked questions will
give you a better understanding of the International Book Number,
how it works, where to get them and so on - and best of luck with your writing career.
What is an ISBN and Why Do I Need One?
The International Book Number consisted of a 10-digit number that uniquely identifies books published internationally. The system was established in 1968 as a standard identification system and is used to identify a title or edition of a title from a specific publisher. Each number is unique to that edition, ie: a hardcover, CD, or eBook format of the same title would each have their own unique number. Today all book databases use the International Book Number system making marketing and distribution far more efficient.
On January 1, 2007 the numbering system was changed to a 13-digit system in order to accommodate the larger capacuty of books that are being published today. All book and book-related products are now required to carry a 13-digit (rather than the 10-digit) ISBN.
If you are publishing a book and want to make sales to bookstores or simply want people to be able to find your book you will need a number. Without a number your book will not be recognized in the book databases and this would undoubtedly hurt your sales.
What is the correct format?
Every number consists of thirteen digits preceded by the letters ISBN. The 13-digit number is divided into five parts, each part separated by a space or hyphen.
What do the numbers signify?
There are five parts to a number. (Example number: 979-1-22065-024-6) The first number is the new EAN product code (979). The second number (1) is the group or country identifier which identifies a national or geographic grouping of publishers. The third number (22065) identifies a particular publisher. The fourth number (024) identifies a specific title or edition of a title. The fifth number (4) is the check digit arrived at by following a special algorithm.
Who should request an ISBN?
Publishers, e-book publishers, audio cassette and video producers, software producers, museums and associations with publishing programs.
Who assigns the numbers?
Numbers are assigned by International Book Number group agencies worldwide coordinated by the International ISBN Agency in Berlin. Numbers are assigned in the United States by R.R. Bowker, an independent agent in the U.S. for this system. http://www.bowker.com/bowkerweb/

Where do I put it?
The ISBN should be printed on the copyright page, and in the lower right hand corner of the back cover of your book. You should use a font size between 9 and 12 points.
