correction: my book was not based on "a private collection held within the Friedman family that contains private correspondence, lecture notes, typescripts and draft works, and much else besides."

It's important for all to know these papers and many more are not only open to all researchers, but that there are a variety of fellowships available to underwrite travel costs. And many are digitized, here is the searchable portion of Friedman's archive: miltonfriedman.hoover.org/co…
