Re: resistivity versus temperature

Heike Kamerlingh Onnes in the early 1900's studied the resistivity of
high purity metals down to 1.2 K or so. Gold and Mercury were easily
purified. I have seen his actual data graphed for Mercury (including
its superconducting transition)

I have a couple of introductory physics texts which show graphs of
the resistivity of various common metals as a function of temperature
(from cryogenic temps to very high). They're very nice looking
graphs but, unhappily, the graphs don't agree with each other at all,
nor do they agree with specific numbers I've found in the Handbook of
Physics & Chemistry. And of course the texts don't reference the
sources from which the graphs have been produced. Do any of you know
