Unfortunately Chris will be unable to complete the unfinished
monographs (having started end of life care) but there is plenty of
interest to any analogue engineer.

I have an issue with his definition of resistor noise power
as the product of open-circuit noise voltage and short-circuit
current. That makes no sense.

There's more than that, probably, but that just jumped out at

The thermal noise power produced by a resistor into a matched load is kT
per hertz.

 Sure, which is what he states.  By mentioning a hot and cold resistor he makes it clear that net energy flow is from hot to cold, and that the T refers to the hot source.
 
But apparently he says that it's four times larger than that.
I'm not making a microsoft account just to download the PDF, so if you want to discuss it further, you could email it to me.
