I'm glad you posted this, Jim, because I meant to mention my experience and forgot. I uploaded a book published in 1942. It didn't have an ISBN and I thought someone had posted here that we had to write "none" if that were the case and not leave it blank, so that is what I did. But it generated an error message that told me specifically that if there were no ISBN number I should leave the space blank. Although the scan was a later printing, apparently, it didn't have an ISBN number. I used the original 1942 edition to validate by, changing the copyright page and the pagination match my edition. Everything else was exactly the same.
