As many readers know, the University of Illinois and the University of Bologna sponsor an annual conference on Constitutional History: Comparative Perspectives. Last year's conference was held in Chicago, with a keynote speech by the incomparable Rosalie Abella of the Supreme Court of Canada. The papers from that conference are now published in the Illinois Law Review and available at this link. These papers represent an extraordinarily rich set of perspectives on issues of constitutional history by scholars from around the world.
This year, the conference will return to Bologna in November. I will post further details and the call for papers soon.
