Just another thought: Is one an ISBN-13 number (13 digits) and the other an ISBN-10 (10 digits)? If so, then I believe that I read on this list a while back (someone please do correct me if I'm wrong) that you should use the 10-digit number. I thought I read a while back that the system checks ISBN numbers during the upload process (if it's incorrect in some manner, one gets an error when trying to upload), and that it could only handle the ISBN-10 numbers (again, correction, please, if necessary). All I can say for sure is that when I recently uploaded a book, I used the ISBN-10 number, and everything went smoothly, but again, since I'm new, someone will probably know much better than I. Still, though, I hope this might be slightly helpful.

How do I know which one to use. Also the book has the same title "Beautiful Lies." However it's a completely different book by a different author and published seven years later than the other one. How do I let somebody know that so they don't just throw it out as a duplicate? It's good to be back scanning again.
