In Germany a book about narcissism[1] rose to popularity after there has been a documentary[2] on national television in which the books author was featured prominently. I cannot comment on the book because I haven't read it but the documentary was interesting[2]. Unfortunately it seems to be available in German only.

One funny thing for me was that the author runs a self-help group for narcissists. On Facebook. I thought this must be as if the anonymous alcoholics would meet at the local pub.
