MLA style is often used in the humanities. In an MLA-style paper, the writer identifies the author and page of each source in parentheses after every reference. That information then directs the reader to more detailed entries on a Works Cited list at the end of the paper.
The Progressive Era. During the period known as the Progressive Era (1890s to about 1920) the U.S. government became increasingly activist in both domestic and foreign policy.
Soon after the Great War, the majority of Americans turned away from concern about foreign affairs, adopting an attitude of live and let live. The 1920s, also known as the roaring twenties and as the new era, were similar to the Progressive Era in that America continued its economic growth and prosperity.
