Book excerpt: The twenties and thirties witnessed dramatic changes in American life: increasing urbanization, technological innovation, cultural upheaval, and economic disaster. In this fascinating book, the prize-winning historian David E. Kyvig describes everyday life in these decades, when automobiles and home electricity became commonplace, when radio and the movies became broadly popular. The details of work life, domestic life, and leisure activities make engrossing reading and bring the era clearly into focus.
