This is a huge topic but i'd be glad to assist,

One of the standard Progressive Era histories is The Search for Order 1877-1920 by Robert H. Wiebe. A little dated, published in 1967, and not without its issues it maintains a spot on most American history shelves. Personally I favor A Fierce Discontent: The Rise and Fall of the Progressive Movement in America by Michael McGerr which covers the Progressive Era as a whole, economically, legally and culturally. It does a good deep dive into the White, Protestant, Middle class roots of the movement and why in the end, it sputtered out. Another one in a similar vein is A Very Different Age: Americans of the Progressive Era by Steven Diner which has a closer look on the common man during the era with a healthy chunk focusing on the common worker, corporations, and unions.

If you're approaching the paper from an Afro-American centric viewpoint than both Huggins Harlem Renaissance and Lewis' When Harlem Was in Vogue have a tighter focus on the flourishing of black intellectualism during the 1920's Harlem Renaissance, James Weldon Johnson features hugely in both books (as well he should.) I'd also recommend Patricia Sullivan's Lift Every Voice: The NAACP and the Making of the Civil Rights Movement which is a fairly groundbreaking history of the earliest years of the NAACP, which Johnson also featured prominently in.

In a American Empire point of view Hans Schmidt's United States occupation of Haiti (1915-1934) is pretty much the standard book on the occupation of Haiti. In a more general view of how American Empire functioned and didn't i'd recommend Aloha Betrayed: Native Hawaiian Resistance to American Colonialism by Noenoe K. Silva and Little Brown Brother: How the United States Purchased and Pacified the Philippine Islands at the Century's turn by Leon Wolff. Both are quality works on American Empire during the 19th century though Wolff can be dry.
