Amazon Self Publishing lets you maintain complete control of your book's publishing process, from start to finish. You choose the editor, cover design, formatting, and marketing for your book, and set your own price. You also retain all the rights to your book, meaning you can self-publish it elsewhere if you wish. Amazon Book Publisher offers a more hands-off approach. After you submit your manuscript, Amazon's team of professionals will take over, handling everything from editing and design to marketing and pricing. You'll still have some input into the process, but ultimately Amazon will make the decisions about how to publish your book. Both options have their pros and cons, so it's important to weigh up your options before deciding which route to go down. If you're looking for complete control over every aspect of your book's publication, then Amazon Self Publishing is the way to go. However, if you're happy to let someone else take care of the nitty-gritty details, then Amazon Book Publisher might be a better fit. Whichever option you choose, Amazon provides a great platform for getting your book out into the world.
