"Out of Many" -- that is the promise of America, and the premise of this book. The underlying dialectic of American history, we believe, is that as a people we need to locate our national unity in the celebration of the differences that exist among us; these differences can be our strength, as long as we affirm the promise of the Declaration. This edition includes a variety of pedagogical features located within the margins of the chapters that will help students study more effectively and productively. Each feature is designed not only to help students grasp the key concepts within the narrative, but also to help direct their study towards success in the course and on the AP exam. - Publisher.
