I have many books that I have been using amazon ISBN. This year, wven though I am not making money yet, I watched Julies ..why to buy the ISBN video.. so now for 2025, I am going to switch and buy my ISBNs so I can start doing ingram sparks or other distros.But I dont want to use money I am not making yet to advertise if I would loose all the reviews when I switch ISBN. QUESTION: what is the fastest way to get the ISBN switch done for about 20 books.
