I think you're being a bit harsh. The central limit theorem does hold for iid rv (independent identically distributed random variables) with finite mean and variance. Now, those assumptions can be relaxed (the rv need not be independent, but they can't be too dependent, and they need not have finite variance, but they can't be too "far out"), and some of the pertinent proofs are only a few decades old; but you can hardly expect a survey with 135 proofs to cover all the subtleties. Some of the other points may be more egregious howlers, but, again, come on - this is not the definite reference for any one of those theorems. |

I wasn't aware of any CLT for iid random variables with infinite variance. Do you have references?
