When do I get the ISBN for cover and copyright page?
I want to buy a sample copy to preview the front/back cover and do the final proofreading of the interior. So just now I uploaded the contents and one-piece cover, with the ISBN areas blank. I got all the way to the end and purchased a copy. But at no point did I see how I get an ISBN. Obviously I'll need to put the ISBN in the copyright page and on the back cover before I do the final run and make it available for purchase. So at what point do I get the ISBN so I can do this and upload the cover and contents again? I did carefully read the "How to get an ISBN" blurb here, but I did not find the answer there. And am I correct in assuming that LuLu will just paste the ISBN on the back cover, so I don't have to do it in my graphics program? Thanks!
