Hi, Becky -
Be sure to see our other thread that indexes the songbooks from this company. Ten years ago, I bought their "complete collection of 72 booklets." I have come across other songbooks in this format, and they appear to be custom songbooks made by Cooperative Recreation Service for various organizations. I'm wondering if your state songbooks are similar custom books that draw from the 72 booklets I have, or if they're books that apply distinctly to the states they're named for.
I see above that Jon Bartlett has a book called "Manitowoc Sings." I'm wondering if that's a city songbook for Manitowoc, Wisconsin (a town I remember fondly).

I also collect school songbooks, and I've found that the songbook publishers often bought songs from Cooperative Recreation Service. Most of the international songs have been translated into English, and I haven't had much luck tracking down original-language sources (or even titles) for those songs.
