While several new forms of entertainment were developed in the 1920's, people still enjoyed the classic pastime of reading a good book. Literature at that time included several different themes, such as romance, comedy, and tragedies, but most books seemed to have the same fundamental ideas. A considerable amount of famous authors based their books on their own personal experiences, ideas, and morals. Some of the most defining books of the era were The Great Gatsby by F. Scott FitzGerald, Babbit by Sinclair Lewis, The Wasteland by T.S. Elliot, and the Sun Also Rises by Ernest Hemingway.
