The Ringling Archives recently collaborated with the Sherman Grinberg Film Library to preserve their Pathe Newsreel SIL 955: The Biggest Show on Earth Thrills the Coolidges from 1928. Funding for this project was received through a grant from the National Film Preservation Foundation.
Over one hundred years of circus history is captured in this project. Route books hold information on people, positions, animals, events, and the circus route. No other unique publication offers as much information on circus routes.
