Hi Jane, If one of your books gets rejected and you don't know why you can write to Gustavo, the administrator who deals with most of that stuff. his address is gustavo.g@xxxxxxxxxxxx He can let you know why a particular book has been rejected. I also recommend that you search the collection to make sure that the book you're planning to submit isn't already there. It doesn't take long to search, and you'll save the validator and admin time if you only submit books you know aren't already in the collection. Hth, Kellie
