Top nine Nine Shift books of 100 years ago

6. THE AGE OF INNOCENCE, by Edith Wharton
   The values, mores, morals and ethics of the previous century are explored in light of the changing times. Wonderful reading.

5. THE 42nd PARALLEL, by John Dos Passos.
  The best book to give you a feeling of the people of the times from 1900 - 1910, the wandering, not just geographically but emotionally, as the perplexing new century poses new challenges for the kids of 100 years ago.

4. THE MUSIC MAN, by Meredith Wilson & Franklin Lacy.
   Written in 1957, but taking place 100 years ago, the music sets the times as well as the words. The opening scene is priceless, with the two salesmen debating whether the times are really changing.
