The fully illustrated Currents of Change includes color plates and black-and-white photographs. Monkhouse, Busch, and Janet Whitmore, a freelance art historian, each contribute an essay to the publication. Monkhouse examines the development of America's artistic identity with the Mississippi River through Longfellow's Song of Hiawatha and Evangeline. Busch uses furnishings and portraits by artists like Thomas Sully and Alexander Roux to trace patterns of patronage and decoration along the river. Whitmore explores the Mississippi River landscape, people, and architecture in paintings by artists such as George Caleb Bingham and Henry Lewis.
