Thanks, M.H. Lee, I was successful in signing in as you suggested. I am presented with a page showing 5 headings. I have two quick questions about them: . . . One heading says "Cover Upload". Why would I upload my cover to Bowker? Another heading says "Barcode Buy Barcode". Now that I have spent money buying my ISBN from Bowker, do I now have to go and buy a barcode from them as well? This book is going to be published via KDP (CreateSpace) on Amazon. I have been told by some people that Amazon supplies a bar code. I wonder if you can straighten me out here. Should I buy a bar code from Bowker or will Amazon (KDP) supply me one for free? Thanks so much for your help.
