Would anyone care to suggest a recent review article (or even resource letter) on the current state, and especially, efficacy, of PER?
I have the famous resource letter from 1999, and am aware of "Reviews in PER" at per-central, among other things. I'm poking to see if there's anything important my google skills have missed.
