I forgot to tell Bill last night over supper that I’ve managed to upload this video clip to YouTube, but I know he’ll be pleased. We were doing some recording, as he helped me prepare for my talk at the American Historical Association conference next Monday, so it was fun for me to go back to this interview, made about four years ago, just as articles for the new edition of the Berkshire Encyclopedia of World History start to come in. Bill explains how it all began, and you can hear it for yourself!
