She had… been picked out to work in Pornosec, the sub-section of the Fiction Department which turned out cheap pornography for distribution among the proles. It was nick-named Muck House by the people who worked in it, she remarked. There she had remained for a year, helping to produce booklets in sealed packets with titles like Spanking Stories or One Night in a Girls’ School, to be bought furtively by proletarian youths who were under the impression that they were buying something illegal.

– George Orwell, 1984
