From 1680 until 1791, only one theater troupe in Paris was allowed to perform the plays of Molière, Corneille, Racine, Voltaire, Beaumarchais, and every other French-language playwright. This troupe, the Comédie-Française, played the works of these authors over 34,000 times in this period. Remarkably, the troupe kept detailed records of their box office receipts for every single one of those performances. These daily receipt registers, as well as the data they contain, are now available online via the Comédie-Française Registers Project.
