We've just noticed that the ASLH's website for the 2015 annual meeting in Washington includes a link to a paper circulated in advance of the conference. It is “Freedmen’s Bureau Courts and the Critique (and Resurgence) of Adversarialism," by Amalia Kessler, Stanford Law School, and it is part of the Friday, 10:45 session, "The Limits of (and Alternatives to) Common-Law Adversarialism":
