Four different versions of the 12th edition were printed. All are divided into six parts, from "Founding the New Nation" (with an initial chapter on prehistory, natives, and European exploration) through "Making Modern America." The six parts are subdivided into a total of 42 chapters spanning 1034 pages. The book's chronology officially ends in the year 2001, though later printings include an additional three paragraphs detailing the 2004 US election as well as September 11. Since then, the incumbent edition of "the American Pageant" included information regarding the 2008 presidential election.
