It is with great delight to report to you that, so far, two classic books on the liturgy, long out of print so far as I know, and very hard to get, have now been put back into print by Nova et Vetera.
Liturgies of the Religious Orders by Archdale A. King
Liturgies of the Primatial Sees by Archdale A. King
The website is in German and Germany, but don't worry, the actual books are in English.
Let's hope we see some of the other titles of King come out from this publisher.
