That’s excellent, Robert. Thank you for sharing it.
That’s very true, but we do have to cut the author a little slack—he was writing that in the 1950’s afterall! 
And there are definitely some gems in there. Published in '59, most physical copies of it are probably either decrepit by now or badly decaying. It’s nice to have it available in some format, so it’s good that you posted it. It probably would never have been re-printed, and in today’s environment*, the chance that it ever will be is infinitesimally small. All physical copies of the book will be gone forever soon, so it is nice to have it available to us in some format.
