You all know someone (perhaps yourself?) who needs this, so, this being a year when we particularly don't want to be throwing our money away on ephemeral junk for Christmas presents, think about purchasing the Summit Choirbook. (Very easy to order online, they take Paypal.)
Not only is it a superlative hymnal, but the Dominicans of the Rosary Shrine are superlative nuns.
If you happened to be in the area, you ought to stop in, and do your prayer life a favor.)
(Say hello to Sr. Virginia for me...)
