Forgive me if this is old news, but I'm not sure that I knew that the liturgical books of Trent are in print from the Vatican. So here we have the Missale Romanum (1570), the Brevarium Romanum (1568), the Caeremoniale Episcoporum (1568), and the Pontificale Romanum (1595-1596).
So now you know what every liturgy geek wants for Christmas. I can think of many books in my collection I would gladly sacrifice to make shelf room for these. And who knows about the future? If the Roman Rite is liberalized enough, and I can think of no reason it shouldn't be, these books might someday serve more than a purely archival purpose.
