Oddly, even in newer books, sometimes the isbn is not printed; I have no idea why, but that is definitely the case. Also, occasionally, they don't scan right, causing the upload to have to be redone because the ssystem doesn't recognize the messed up isbn as valid, which it isn't, of course. Really, I can't see getting very excited about a missing isbn. If its not there, and you feel like adding it, then go for it. If not, its hardly something to get very upset about, since Jesse himself has said they don't have to be included, and he didn't say that was true just for older books. I'm all for quality, and I do tend to put in the isbn. But there is such a world of difference between a missing isbn or even missing page numbers, as opposed to garbled text that is so mangled as to preclude one's understanding of what the author is trying to convey. I wish we could keep that fact in mind when discussing quality of books. Mary
