Yes — and many authors do this to increase reach. This is called “going wide.”
You can publish your book on:
- Amazon KDP (for Kindle + print)
- IngramSpark (for wider bookstore/library distribution)
- Draft2Digital, Kobo, Google Play, and others for ebooks
Just ensure you’re not in KDP Select, which requires ebook exclusivity to Amazon. Print can be distributed anywhere, even while staying on Amazon.
