When I submit a book that I own, I usually put my e-mail address in the comments section for validators, indicating that if there's any problem with the scan, they can contact me directly and I'll rescan as appropriate. If it's a library book, I don't usually do this because it is probable that I will no longer have the book by the time it gets validated...which is not to say that I wouldn't check it out again if needed. My name shows as the submitter regardless. Peace and Hope, Donna
