an excellent paper.

I like the comments about how in a survey of 165 papers on electroplated 
copper that data on electrical resistivity are nearly non-existent.

And the discussion about how silver plating *used* to be good for tank 
coils because the phosphorous in the copper reduced the copper 
conductivity, and the silver was a pure, thick high conductivity 
coating, but that today (1970) that wasn't the case.

Then the comments at the end about how modern plating is so far from a 
uniform single metal layer..
