Hi, I downloaded two books that I'm interested in validating. Both were submitted by Bookshare volunteers, but both also indicated that they were of Publisher quality, not excellent quality. For those who submit books, when do you decide to mark a scan as publisher quality, and not just Excellent. I ask because the scanning process almost inevitably introduces a few errors, so I was curious what your distinction was. For instance, is it a particularly high ranked spelling result from Kurzweil, or something else? The first book I'm reviewing has thus far had no errors, so the ranking seems reasonably accurate, but I was just a little surprised. I guess I expected only books coming from the Bookshare office to be marked in such a fashion. Thanks, Nancy
