The Journal of Policy History has published my article, "How Talking Became Human Subjects Research: The Federal Regulation of the Social Sciences, 1965–1991." As permitted by the transfer of copyright, I have posted a PDF on my personal website: http://www.schrag.info/research/howtalking.html.
Not much has changed since I posted a version on SSRN in April 2008. The major changes come in the "medical origins" section; the earlier draft underestimated the strength of social scientists' opposition to IRB rules in the late 1960s. Also, the new version better explains the origins of Ithiel de Sola Pool's concern about IRBs (see p. 18).
