Don't forget to check out the books available here on MobileRead. Many of them are more carefully assembled e-books than those available on Project Gutenberg. For example I recently read "Three Men in a Boat (To Say Nothing of the Dog)" by Jerome K Jerome from the library here, it is a beautifully constructed epub that includes illustrations, and there are other fine examples too.
