A poster in my survey thread asked for suggestions on settings for Mass, using chant and Latin; if memory serves, he was especially interested in the Sanctus.
I deleted his comment, there, because I wanted that thread to focus on the survey I am conducting. But I would welcome any such suggestions here.
My suggestion: Jubilate Deo, the booklet issued by Pope Paul VI. Also, check out the New Liturgical Movement site, linked in my section of bookmarks. That's all I can offer very quickly.
