This book is not due out until August. However, you can view a short discussion by Joe Hicks about Professor Gates' new book here. From what Mr. Hicks says about the book, it is sure to generate quite a bit of controversey and discussion.
I've always enjoyed watching Gates on PBS' History Detectives and thought he did a fair job in his role in last year's PBS documentary about Abraham Lincoln.
I'm looking forward to reading this book.
