Under the sponsorship of the American "Law Institute and subsequently of the University of Michigan, with the efficient assistance of the Faculty, notably of Hessel E. Yntema as editor, I published the first volume of a work on conflicts law in 1945. A second volume has just followed, after a long delay caused by the vicissitudes of postwar printing. The greater part of a third volume has been readied in the meantime, but its date of publication is not yet fixed.

The task consists in surveying the existing and proposed conflicts rules of the world and in ascertaining their background, purposes, and social effects as exactly as the available sources permit. We should be able by such research to devote the manifold advantages of comparative studies to the urgent needs of a branch of law which at present bears the name of private international law as if by irony, like lucus a non lucendo.
