Downside of using Free ISBN
Using a free ISBN to publish ebook is not a big deal, as you can unpublish anytime and republish using a different ISBN without any issues. But the same is not true for print books, as you can’t completely take down a print book from the retailer website even after unpublishing. Republishing the print book may create copyright issues.
It is highly recommended to use your own ISBN to publish a print book. For ebook it’s optional. But, recommended for better distribution and professional look. Below are downsides of using a Free ISBN to self-publish a book:
1. Limited Distribution:
Free ISBNs are offered by the self-publishing platforms like Amazon KDP. That free ISBN can’t be used out of Amazon. Amazon KDP has an expanded book distribution feature that lets authors publish their books on other retailer websites through Amazon KDP.
The distribution network of Amazon KDP Expanded distribution is small compared to IngramSpark. Also, your book has to meet Expanded Book Distribution terms to use this feature.
Your book distribution will be locked into one publishing platform and its distribution network. You can’t change the ISBN of your book once it is published. Furthermore, republishing a printed book is difficult.
2. Unprofessional Look:
Free ISBN comes with self-publishing platform imprint name. Your book may appear low quality to a book retailer and readers because of your book imprint name. The Amazon KDP imprint name “Independently Published” is popular and easily recognizable. The booksellers will easily know that your book is self-published through Amazon KDP.
