Sitting on my desk right now: (and calling my naaaame....)
The Liturgy Betrayed: Denis Crouan (purchased for $2 off amazon!)
The Spirit of the Liturgy: Romano Guardini (Ratzinger mentions it a bunch in his book, bought brand-new with gift card. I'm also pleasantly surprised at how thin it is!)
The Organic Development of the Liturgy: Alcuin Reid (also bought with gift card. However, *not* pleasantly surprised at how thick it is! This could take me awhile...)
Sing Like a Catholic: Jeffrey Tucker (borrowed from a friend)
The Difference God Makes: Francis Cardinal George (given to me at sitting on my desk since Christmas...)
An Introduction to the Interpretation of Gregorian Chant: Agustoni/Goeschl (library)
A Short Treatise on Gregorian Accompaniment: Bragers (library)
What Happened at Vatican II: O'Malley (waiting for me at the library! must pick up soon!)
The Reform of the Reform--A Liturgical Debate: Kocik (ordered from ILL)
Vatican II--Renewal Within Tradition: Lamb/Levering ("waiting in queue" for me at library)
wow. that is a lot. But, I'm super-excited! If I get through all of these, it will make quite a dent in my list of "must-read-books in your lifetime regarding your favorite topic..." and who knows when will be the next time that I don't have a full-time job during the summer...
EDIT:
I also received from interlibrary loan, the book "Turning Towards the Lord" by U.M. Lang.
(this brings the current stack of books on the floor to 7.5" high...)
