This multivolume history marks a new beginning in the study of American literature. The first Cambridge History of American Literature (1917) helped introduce a new branch of English writing. The Literary History of the United States, assembled thirty years later under the aegis of Robert E. Spiller, helped establish a new field of academic study. This History embodies the work of a generation of Americanists who have redrawn the boundaries of the field. Trained mainly in the 1960s and early 1970s, representing the broad spectrum of both new and established directions in all branches of American writing, these scholars and critics have shaped, and continue to shape, what has become a major area of modern literary scholarship.

Over the past three decades, Americanist literary criticism has expanded from a border province into a center of humanist studies. The vitality of the field is reflected in the rising interest in American literature nationally and globally, in the scope of scholarly activity, and in the polemical intensity of debate. Significantly, American texts have come to provide a major focus for inter- and cross-disciplinary investigation. Gender studies, ethnic studies, and popular-culture studies, among others, have penetrated to all corners of the profession, but perhaps their single largest base is American literature. The same is true with regard to controversies over multiculturalism and canon formation: the issues are transhistorical and transcultural, but the debates themselves have often turned on American books.
