Today's trade paperback list features an especially impressive milestone—it's the 100th week for Robert T. Kiyosaki's Rich Dad, Poor Dad. That Warner title, along with four others in the Rich Dad series—The Cash Flow Quadrant, Rich Dad's Guide to Investing, Rich Dad's Rich Kid, Smart Kid and Rich Dad's Retire Young, Retire Rich—have sold more than three million copies combined (Rich Dad, Poor Dad itself currently has two million in print). Success is solid enough that Warner is publishing Kiyosaki's sixth book, Rich Dad's Prophecy, in hardcover this October—a 200,000 first printing is planned.
