Lady Chatterley's Lover — D.H. Lawrence

D.H. Lawrence's explicit novel about an aristocratic woman and her gamekeeper was banned in Britain for 32 years, making it the longest-standing ban among the top 10. Penguin Books's 1960 decision to publish the unexpurgated text led to the celebrated obscenity trial where the prosecution asked, 'Is it a book you would wish your wife or servants to read?'—a question that became emblematic of establishment paternalism.
