The Superior Formatting Publishing version isn’t a Barnes and Noble book, so this isn’t the work of a rogue Nook marketer from B&N. Rather, it’s likely that Superior Formatting Publishing ported its Kindle version of War and Peace over to the Nook — doing a search and replace to make sure that any Kindle references they’d inserted, such as in the advertising at the end of the book about their fine Kindle products, were simply changed to Nook.
