I have created several paperback books on Lulu. I do wish that when e books are created at the beginning it should state that any title must either be E PUB on lulu OR Kindle on Amazon or any other platform. You cannot have on BOTH. This causes great confusion. You will find in the agreements that you automatically sign in either Lulu.com or Amazon!
Wether or not people call ther book different things on each site to get around this i dont know!
Please be specific the e book authors!
