The focus of Reading the Twentieth Century is on the role of the United States in the world in the twentieth century, after the nation became a major world player. Readings include public documents, memoirs, and media comments, many of which have never been published before. The book is structured in such a way that portions can be assigned to students, and the order of presentation is such that instructors can assign sections chronologically or thematically. Though highly informative, the editor’s chapter introductions and the document head notes are brief, designed only to introduce the subjects so that the documents can speak for themselves.
