Books on Progressive Era (America 1890 - 1920)

I just started a social history that was met with lot of critical praise in its day. A Very Different Age Americans of the Progressive Era; Steven Diner (1998).

This is a fascinating time in American history. Lot's of the now familiar modern themes are emerging: mass comm, electric tech, tele-comm (telegraph), mass transit, labor movement, econ chasms, etc.

I'd like to get more into this period. Please suggest your favorite books regarding Progressive Era (America 1890 - 1920).
