OCP Advertises Latin Book!
It's been out, but not pushed much. But I got this in my regular mailing from them:
OCP offers Latin resources to make Latin chant part of your community's Sunday worship.
Particularly, they show a supplement called Laus Tibi, Christe, a book chocked full of Latin hymns and chants. Although it was originally intended to supplement the latest JourneysongS hymnal, you could add it to just about anything. Their best product to date, IMO.
