I added an edition of a book that was fundamentally identical to the existing book except that it was hardcover, and had a different ISBN/EAN. Could you add an "add edition" link that clones an existing entry (perhaps blanking out some fields like ISBN and format) and then allows editing, rather than requiring one start from a blank entry and copy and paste?
It would also be nice to be able to select the cover from the existing covers, as it's quite likely that other editions will have the same cover as existing editions.
