I have a 1909 edition and a modern reprint of the original missal. Both are invaluable in being able to say the "Traditional" Mass in English instead of Latin. You not only get the Ordinary and Canon of the Mass, but Votive Masses, Marriage Service, baptism, confirmation, confession, Extreme Unction, and much, much more. If you are serious in saying the Traditional Mass in English, this is the book, in my opinion, to buy.
