Ten Days in a Mad-house Illustrated and Annotated

In 1887, reporter Nellie Bly was admitted to the Blackwell's Island Lunatic Asylum in order to do undercover reporting on the conditions there, as part of the assignment given to her by Joseph Pulitzer at the New York World. The resulting reports were published later that year in a book, Ten days in a mad-house, and influenced substantial changes, followed by the closure of the asylum.
