I am at the point in Amazon KDP where I am wanting to see a preview of my novel. I do not have an ISBN number yet because I am still only wanting to preview and not publish. Amazon asks if I want a free ISBN number from them or if I should provide my own. If I choose to have Amazon provide the ISBN, am I stuck with it or can I back out and later add my own? The reason for this is I cannot upload a manuscript to preview without a valid ISBN number.
I had heard if you take an Amazon ISBN number, and then later use your own, you lose all the Amazon history and have to start from scratch. If that is the case I will have to buy one.
