The study in this report focuses on four historical periods and five textbooks. The four historical periods are: (1) The European Settlement of North America (1492-1660); (2) Colonial America (1660-1763); (3) The Nation's Founding (1763-1789); and (4) The New Deal (1933-1940). Three of the 5 textbooks are intended for regular high school American history classes and the remaining 2 are intended for Advanced Placement American history classes. While the study does not provide a comprehensive judgment of how American history textbooks cover American history, but its selective analysis provides a window into the general operations of American history textbooks.
