A New Literary History Of America (Harvard Univ., $49.95) is an immense critical achievement. The more than 200 essays commissioned by the editors, Greil Marcus and Werner Sollors, capture the plurality of American historical and cultural experience in all its complexity, fluidity, and contradiction. The editors broadly and flexibly interpret “literary,” applying the term not only to texts and authors, but to cultural moments and ideas. A stadium-sized roster of essayists, including Jonathan Lethem, Arnold Rampersad, Kara Walker, and Camille Paglia, explore such disparate topics as Martin Luther King, Jr.’s “Letter from Birmingham Jail,” the origins of the European concept of a “New World,” and an exploration of “hardboiled” as a state of mind. The book’s amazing diversity is unified by a single thread, which is simply, as Marcus and Sollors state, “speech, in many forms.” Thus, this anthology represents America as an intersection of voices and experiences speaking to each other, calling out, protesting, creating, and recreating anew. This is a vital book for any student (or product) of American culture.
