Joseph Shannon (fl. c. 1850 - 1869) produced a series of New York City almanacs and fact books entitled Manual of the Corporation of The City of New York . Shannon's Manual is very similar to the more common manual issued by Valentine. The production of this annual manual was the responsibility of the Clerk of the Common Council of the City of New York, a position held at different times by both Shannon and Valentine. The manual included facts about the City of New York, city council information, city history, and reported on the progress of public works such as Central Park.
