Don't know if you care about "in the wild" sightings or not, but the Chicago Public Library had a display copy of "Tempering of Men" in the popular fiction mini-library. (It's like a branch library that's inside the Harold Washington Library, on the first floor. It's popular books only and in theory it's faster to nip in, grab your best-seller, and check out. In practice, check out lines are longer there than they are upstairs in the main library.)
