Cialdini also seems to have put out the same info in a textbook (which does not read like one) "Influence, Science and Practice." Amazon reviews say it is nearly identical, except it has chapter reviews and problems. I only mention this because this is the version that was available at my 2 nearest library systems. Very good reading a quarter of the way in-- so thanks for the tip.

EY-- what other books are in the "own 3 copy" club?
