Debts accumulate in projects such as this one. Those familiar with the work of earlier scholars will recognize at once how much I have depended on my predecessors for guidance and insight. I have learned from every book consulted, and have profited from reading even when I disagreed. Some debts, however, are larger than others; some deserve specific mention, while others can simply be assumed as part of the legacy bestowed by those writers who have set the parameters for the field of American historical studies. Accordingly this essay mentions only those works either uncited in the notes or singularly important to me in the effort to construct an interpretive framework.
