I just scanned a quick little science fiction fave from the 60s, The Revolving Boy by Gertrude Friedberg. I have the 1966 original paperback copy published by Ace Books, Doubleday and Co. There isn't an ISBN. I looked in Amazon.com and they list a 1980 version, by Del Rey publishers, with an "ASIN" number, whatever that is. Then I checked Barnes and Noble, and they list a 1980 version by Random House with the ISBN same as the ASIN. All are the same copywrite author. So when I submit this, I will put the original 1966 copyright date as that's the edition I have, but I don't have an ISBN... What should I do? Explain all this in the scanners comments box? I have heard that validators sometimes don't read the messages the scanners put in. Liz in Seattle Liz Halperin Seattle, WA lizzers@xxxxxxxxxxx
