Absolutely! In fact, we encourage authors to include links to every retailer where their book is available.
Many of our readers shop at retailers other than Amazon, including Apple Books, Barnes & Noble Nook, Google Play Books, and Kobo. By providing links to multiple retailers, you make it easier for more readers to discover and download your book from the store they already use.
When readers subscribe, they tell us which ebook retailers they prefer. Our personalized newsletters use those preferences to show readers the retailer links that are most relevant to them whenever possible.
Even if your book is available only through Amazon, you're still welcome to promote it with The Fussy Librarian. However, if your book is published wide, including all of your retailer links helps maximize your potential audience.
