The Mechanics' Institute Library and Chess Room is an historic membership library, cultural event center, and chess club located in the Financial District of San Francisco, California at 57 Post Street. Founded in 1854 to serve the vocational needs of out-of-work gold miners, the Institute today is a favorite of avid readers, writers, downtown employees, students, film lovers, chess players, and the 21st century nomadic worker who needs a quiet place to plug in a laptop and do research.
