I posted an identical book with an ISBN not recognized by the system: 0030420365. So the system put in a "fake" ISBN of 127714. Seeing that only the last digit is different, I am thinking that whoever entered this into the system accidentally put a "9" instead of a "5." I tried to edit the book data, but it will not allow me to edit ISBNs, and it did not recognize the true ISBN when I posted it.
