"This book will have the same noble goal as my television show: to change the world one factual error at a time," Colbert said Tuesday in a statement issued by Warner Books.
Colbert's book, currently untitled, is scheduled to come out in the fall of 2007. Colbert, a longtime fixture on Stewart's "Daily Show," now hosts "The Colbert Report," also aired on Comedy Central.
Colbert also has a background with words. He contributed to "America (The Book)," co-authored "Wigfield" with Amy Sedaris and Paul Dinello and is credited with coining "truthiness," named Word of the Year for 2005 by the American Dialect Society.
"Truthiness" is the quality of stating concepts one wishes or believes to be true, rather than the facts.
