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.
The unwitting hilarity of a publisher doing a “find and replace” and accidentally changing the text of a canonical work of Western thought is alarming. Many versions of e-books are from similar outfits, that distribute public domain works formatted for Kindle or Nook at the lowest possible prices. The great democratizing factor of the ebook formats – that anyone can easily distribute – can also mean that readers can never be quite sure that they are viewing the texts as the author intended.
