The author, Lars Cornelissen, of “Neoliberalism and Its Hegemonic Crisis,” erred in stating that in her book, Milton Friedman: The Last Conservative, Jennifer Burns made use of “a private collection held within the Friedman family that contains private correspondence, lecture notes, typescripts and draft works, and much else besides.” Burns instead relied on the Milton Friedman papers at the Hoover Institution Library and Archive, a professional archive open to all researchers, as noted in the book’s footnotes, note on sources, and acknowledgements.
