Greetings Fellow Wordsmiths! I am getting ready to publish a science fiction novel and I wanted to publish both on KDP and Ingram Spark - I am going to publish Kindle, Paperback, and possible their beta hard cover on Amazon. I am also going to do the same on Ingram Sparks. I bought a block of 100 ISBNs so I have those available. My question is, do I assign the same ISBN to the EBook for Kindle and Ingram Sparks? Do I assign another ISBN to both Kindle and Ingram Sparks paperbacks that is the same? And finally - Do I assign another ISBN to both Kindle and Ingram Sparks hard covers that is the same? So that each format has the same ISBN regardless of distribution/seller platform? Or do I use the ASIN for the Amazon Kindle EBook? Thanks for your help!
