Interesting Book - Still Relevant Today

I recently came across an outstanding little book at Google Books:

Memoirs of the Lutheran Liturgical Association, Volumes 1-4

This book contains articles on the Lutheran Liturgy by various sources, and while the book predates the twentieth century, there is a ton of material there that will bring the history of the Western Liturgy into the eyes of anyone. I especially recommend it to seminary studients, no matter your background.
