I was about to bring a really polished perfect version of Palms Inn into the published by you package at Lulu.com so it could go to Barnes and Nobles. But before doing so I decided to look at what options I have and investigated createspace bit. I found that they have lower production cost and every book you publish can go on Amazon free of charge. But is the ISBN createspace gives you, is that yours? Is it free? Can you use it to submit to other book stores with that ISBN? Does createspace have a simialr package that may go to Barnes and Nobles? I recently read a blog about someone saying it was a good idea to use both. But will the rules of create space and Lulu.com allow that sort of ISBN use? I'm just curious if anybody really kind of know the right route here?
