Since Yesterday is Frederick Lewis Allen's sequel to Only Yesterday. Only Yesterday is an informative and popular tell-all history book about American life in the 1920s. Since Yesterday turns this same witty and empathetic energy towards the Great Depression and 1930s America. Excerpt: “Ever since, in Only Yesterday, I tried to tell the story of life in the United States during the nineteen-twenties I have had it in the back of my mind that someday I might make a similar attempt for the nineteen-thirties. I began work on the project late in 1938 and had it three-quarters done by the latter part of the summer of 1939, though I did not yet know how the story would end.”
