Hi Gisela, If the submitter of the book has written in the comments field that this book is a resubmit, a fixed up version of something from the collection, then you should accept it, after looking it over of course. If it's a duplicate but the submitter hasn't mentioned that it was an intentional resubmit then you might want to mention it here so that someone with Kurzweil's ranked spelling feature at their disposal can check it out. I hope this helps and that I didn't just add to the confusion. <grin> Kellie
