What is an ISBN?
ISBN stands for International Standard Book Number. It has 13 digits and consists of 5 sections separated by spaces or hyphens. The first group is the prefix element. It is either 978 or 979. Next is the registration group. It’s between 1 and 5 digits and identifies the country, geographic region, or language. The third is the registrant, up to 7 digits and identifies the publisher or imprints. The publication element is fourth. It has up to 6 digits and identifies the particular edition and format of a specific title. The last is the single check digit. It’s used in some fancy-schmancy mathematical formula you and I can’t care less about and validates the ISBN.
Now that I know what it is, what the heck is an ISBN used for?
An ISBN is a product identifier. That’s it. The number is assigned to publications and used by publishers, booksellers, libraries, internet retailers and others to order, record sales, or manage stock. The ISBN identifies the registrant as well as the specific title, edition, and format. ISBNs are assigned to single publications such as books, but not to serial publications such as journals or newspapers. Any book made publicly available, for sale or free, can be identified by an ISBN, but so can individual chapters of books or articles from journals and periodicals. An ebook doesn’t require an ISBN, but a publisher can attach one, if desired. However, each format (e.g. paperback, hardcover, EPUB, .pdf) requires a separate number, so if you choose to assign an ISBN to an ebook, it must have a different number than the paperback version.
What does that have to do with the copyright?
Nada, zilch, zippo. The ISBN is an identifier. Simply having an ISBN on a book doesn’t convey any legal or copyright protection. Nor does it take any away from the author. The ISBN only identifies the publisher of a particular edition. In effect, the person or company who ponied up for the ISBN.
How do you get an ISBN?
You have to buy it and they’re not cheap. The only authorized representative in the United States to sell ISBNs is a company called Bowker. ISBNS are $125 for a single ISBN, but they have reduced rates if you buy in bulk.
Does a self-published author need an ISBN?
Maybe. Maybe not. If you only plan to publish an ebook then an ISBN isn’t necessary. Paperbacks or hardcovers are different stories. Companies such as CreateSpace will give you an ISBN for free if you publish with them. Again, this has nothing to do with copyright. The number will only identify the publisher as CreateSpace, and you will still be the author and retain all rights.
If you plan to market mostly ebooks and only sell hard or softcovers through a website or conventions then this is a good cheap way to go. However, you can pretty much forget about bookstores. Most are loathe to take on self-published authors anyway, but a CreateSpace ISBN is the kiss of death. First of all, it’s an Amazon company and indy bookstores don’t want to throw any more money at the Big A. The biggest reason is that companies like CreateSpace don’t have a buy-back option for booksellers, so a retailer can’t return unsold books. Indy bookstores aren’t particularly welcoming to self-published authors, but you may be able to talk a few into carrying your book if you have an ISBN from a company that offers buy-backs, so they’re not out any money if your book doesn’t sell. This means becoming your own publisher. Don’t worry, you don’t need to invest in typesetting equipment. Simply buy an ISBN and use a company that offers buy-back, such as IngramSpark. It won’t guarantee sales, of course, but may put you one step closer. Good luck.
