Already in distinctive company as an American president, George W. Bush seeks to join an even more select group: president and top-selling author. Since the New York Times began its weekly lists of best-sellers in 1942, only six of the 13 men who have served as the nation's chief executive have placed books at the top spot for nonfiction, none while president. (Snip) George W. Bush's book, "Decision Points," is set for release this fall by Crown Publishers. It's not an autobiography, Mr. Bush said, but an analysis of key moments in his life, from quitting drinking to invading Iraq.
