Personally, I would have preferred am original spelling version but modernized was arguably less distracting. If you read this book, be advised that there are both brief footnotes - primarily glosses on archaic vocabulary - *and* more substantial endnotes. There's a good history of the 1559 book following the edition proper, going back to the Edwardian prayer books and forward to the 1662, discussing their textual and doctrinal relationship.
