'This textbook is based on the College Entrance Examination Board test in Advanced Placement United States History. The test is a standard on the subject, covering what most students in the United States study in high school and college, so we treat it as the best reference.
The text was reorganized and edited in November 2008 to be closer to the content and organization the college board requires. The content was carefully chosen for significance and interest. We welcome reader feedback and suggestions for improvement.'
