Information Booster
The Book: V.D. Savarkar's The Indian War of Independence - 1857, originally published in 1909.
The Ban: The British government swiftly banned the book before its publication due to its revolutionary content, which re-interpreted the Revolt of 1857 as the first organized "War of Independence" rather than a mere "Sepoy Mutiny."
The Method: To circumvent the ban and get the book into the hands of Indian revolutionaries, copies were secretly printed and published in the Netherlands and then smuggled into India and England. One famous method of smuggling was disguising the revolutionary text with the cover of a popular, harmless work of fiction, such as Charles Dickens' The Posthumous Papers of the Pickwick Club (often shortened to The Pickwick Papers), specifically using the label "Random Papers of the Pickwick Club".
