It's called The Beauty of God's House, and is edited by Francesca Murphy, and sounds really good.

When Mr. Caldecott was nearing death, I posted a prayer request for him here. But when he actually died, I was silent. That was because so many notices and eulogies appeared on the web that I couldn't sort through them all, and never picked one or two to post here. Nor did I feel like I knew his work well enough to say anything general. So I'll let the notice of the book at the link above serve as an obituary. And I look forward to reading the book.
