Joe, I sure wish I had this much time on my hands! I have several of the books you've listed, as well as other grade levels of some of the above editions, but it's going to be some time before I can post the indices (of course, now that I have your snail address...)

(I never did find the MacMillan book with Four White Horses, but I have since found it in 3 other books at school! I'll look for them tomorrow)
