Annuntio vobis gaudium magnum: habemus liturgia horarum.
That’s right, the 4-volume Latin Liturgy of the Hours is (are?) back, after several years of being, unbelievably, out of print.
You can put in a pre-order now. (Disclaimer: I did email them several days ago and have not heard back – but that’s not too surprising, honestly.)
It makes the perfect gift for the N.O.-friendly trad in your life.
