Publishing via Lulu and CreateSpace
Is it permitted to have a CreateSpace paperback on Amazon and publish a hardcover of the same title through Lulu, using of course different ISBNs each time. Is there no conflict there from Lulu's perspective? CS doesn't offer hardcover so I imagine this is ok? Lulu says they are the distributor not the publisher, so they are just distributing my hardcover version and CS distributes my paperback edition. Right?
