Prosperity and Thrift: The Coolidge Era and the Consumer Economy, 1921-1929 assembles a wide array of Library of Congress source materials from the 1920s that document the widespread prosperity of the Coolidge years, the nation's transition to a mass consumer economy, and the role of government in this transition. The collection includes papers, books, pamphlets, legislative documents, consumer and trade journals, photographs, films and audio. The collection is particularly strong in advertising and mass-marketing materials and will be of special interest to those seeking to understand economic and political forces at work in the 1920s.
