Source on my closed church "project."

I found a source for information on closed churches. The Kansas City Public Library has This Far by Faith, a two volume book on the Diocese of Kansas City, St. Joseph, the second volume of which is a compilation of parish histories. Unfortunately, they've only got one copy and it doesn't circulate, so I'll have to find some time to spend there. Hopefully, I'll be able to go back to the parish churches I've already featured and get some details, as well as perhaps identify some additional churches that have been supressed, demolished, etc.
