An ISBN number is essential for paperback and hardcover books.

Make a Living as a Professional Self-Published AuthorAs you step into the realm of self-publishing, you may wonder, “What is the importance of an ISBN number or self-published books?” The International Standard Book Number (ISBN) is a 13-digit code that plays a crucial role in distinguishing your literary creation. This guide provides an in-depth understanding of how ISBNs can shape your self-publishing journey.

ISBN, a unique identifier, is an asset in the extensive literary marketplace. It helps your book carve out its space in the overcrowded arena. If you’re a self-published author striving for visibility, an ISBN can be your key tool.

In this article, we will delve into the importance of an ISBN, discussing how it affects your book’s distribution on platforms like Amazon and beyond.

ISBN and Libraries: An Indispensable Duo

Have you ever dreamt of seeing your self-published book nestled among classics in a library? That dream could become a reality with the power of an ISBN. Libraries, in their quest for systematic categorization, prefer books with an ISBN. It is this number that makes your book discoverable among thousands.

Obtaining an ISBN could be the first step in getting your book into libraries. As well as aiding in cataloging, an ISBN can also play a role in book sales in these establishments. It is an invaluable asset when your objective is to reach more readers via libraries.

An LOCC number is another requirement of many libraries, and this too can only be obtained if you have your own unique ISBN. This can be sought through the Library of Congress website.

ISBN: Your Stepping Stone to Bookstores

Penetrating the formidable fortress of bookstores can be a daunting task for many self-published authors. This is where owning a unique ISBN could work as your secret weapon. The ISBN serves as a testament of credibility, which could catch the attention of bookstore owners.

Bookstores will not generally stock self-published books, and one of the clues is using the ISBN numbers provided by Amazon and other platforms. If you want to increase your chances of getting your self-published books on bookstore shelves, owning an ISBN is a step in the right direction.

A unique ISBN can be your ticket to get into the bookstore industry. It’s your own ISBN number with your imprint (also called a publishing company) that sets you apart, increasing your chances to be noticed and stocked.

Harnessing the Power of ISBN for Effective Book Distribution

Effective book distribution can be significantly bolstered with the aid of an ISBN. An ISBN ensures that your book is distinguishably identified in the crowded world of digital publishing. This can be your tool to stand out and get noticed by prospective readers.

When you register your unique ISBN and imprint on your book, you also enhance your book’s searchability. This is especially beneficial on platforms like Amazon, where you compete with millions of other titles.

Being the publisher of your book brings additional perks. As the publisher, you get to choose the name of your “publishing company,” effectively creating a unique imprint. A wisely chosen imprint can boost your search rankings on Amazon, adding to your book’s visibility.

Carving a Professional Image with an ISBN

In the competitive realm of self-publishing, crafting a professional image is integral to the success of your book. By using your own unique ISBN number and publishing imprint, you create a professional façade that can potentially garner more readers.

A unique ISBN does not just make you look professional. It actually makes you the publisher of your book, which comes with its own set of advantages. You have more control over your work and the way it’s marketed and distributed.

Moreover, being listed in the “Books In Print” database lends another layer of credibility to your book. By purchasing an ISBN and filling in all the required details in the book database, your book is automatically listed in this highly sought-after database. This bolsters your book’s professional appeal and increases its visibility among the right circles.

Weighing the Cost of ISBN

While ISBN holds several advantages for a self-published author, its cost can be a deterrent. In the United States, a single ISBN is priced at $125, although buying a block of 100 can bring down the per unit price to $5.

However, if you’re selling only on platforms like Amazon, you can avoid this expense. These online booksellers offer their own internal book tracking numbers. Thus, you might not need an ISBN if your sales are restricted to such platforms.

That said, remember that these online booksellers’ internal tracking numbers may limit your book’s visibility to their platforms. So, if you’re planning to expand your distribution channels, investing in an ISBN could be worth considering.

Decoding the ISBN Mystery: To Buy or Not to Buy

As we’ve discussed, an ISBN is a strategic tool that can enhance your book’s visibility and distribution. But should you buy your own, or rely on the ones provided by self-publishing companies? To answer that, let’s consider some potential advantages and disadvantages.

If you’re looking to sell through physical bookstores or attract libraries, purchasing an ISBN may be beneficial. However, if your main sales platform is Amazon or similar sites, you might want to avoid this expense. It is essential to evaluate your distribution strategy and make an informed decision.

Remember that an ISBN is more than just a number. It’s a unique identifier that can aid in classifying your book correctly so that book sellers can find it and the information about it. It’s a powerful tool that, if used strategically, can enhance your book’s presence in the literary world.

What Does the ISBN Number Mean?

ISBN barcode for booksThe International Standard Book Number (ISBN) is a unique numeric commercial book identifier that is intended to be unique to each edition and variation (except reprintings) of a book. It is a 13-digit code, divided into five parts, each of which has a particular meaning. The first part, the prefix element, the second part, the registration group, the third part, the registrant, the fourth part, the publication, and the fifth part, the check digit, are all discussed below.

The first part of an ISBN number, the Prefix Element, always begins with the digits 978 or 979. This is a relatively recent change implemented in 2007 to integrate ISBN numbers into the global standard of the European Article Number (EAN) system, which is used by retailers for inventory and sales purposes. These three digits effectively signify that the product being identified is a book.

The second part of the ISBN is the Registration Group Element. This part can be one to five digits long and identifies the country, geographical region, or language area where the book was published. For example, “0” and “1” denote English-speaking countries such as the United States, the UK, and Australia, while “2” signifies French-speaking areas, and “7” represents People’s Republic of China.

The third part, the Registrant Element, can vary from one to seven digits long, depending on the length of the Registration Group Element. This part of the ISBN identifies the specific publisher of the book. Each publisher has a unique Registrant Element that is used across all of the books that they publish. Larger publishers tend to have shorter Registrant Elements, which allows them to have more unique Publication Elements, given that the total length of the ISBN remains the same.

The fourth part of the ISBN is the Publication Element. This can vary in length, depending on the length of the Registrant Element, and it identifies the specific edition and format of a book. For example, a paperback edition of a book will have a different Publication Element from the hardback edition of the same book.

Finally, the last part of the ISBN is the Check Digit. This is always a single digit, which can range from 0 to 9 or can be an X for 10. This digit is calculated based on a mathematical formula that takes into account all of the other digits in the ISBN. Its purpose is to validate the rest of the number and protect against transcription errors. If a single digit in the ISBN is incorrect or mistyped, the check digit will not compute correctly, alerting someone that there has been an error in the ISBN.

In summary, an ISBN is a complex identifier that contains a wealth of information about a book’s origin, publisher, edition, and format. By understanding each part of an ISBN, one can gain insight into the various aspects of a book’s identity.


To sum it up, an ISBN could be your strongest ally in the world of self-publishing. Whether it’s getting your book on library shelves, enhancing your book’s professional appeal, or increasing your work’s visibility, an ISBN has an influential role to play.

However, before you take the plunge, it’s vital to weigh the potential benefits against the cost. Remember, each author’s journey is unique, and there’s no one-size-fits-all solution. Consider your publishing goals, evaluate your strategy, and make a choice that works best for you.

Deciding on whether to purchase an ISBN is not a decision to be taken lightly. As a self-published author, it’s a critical step that can potentially shape your book’s success. Take the time to understand how it can impact your work and make an informed choice. Happy publishing!
