In 1963 in the UK, Cain's Book was one of many books and magazines seized by the police at a bookseller's shop in Sheffield. Its publisher, John Calder, sought a separate trial for Cain's Book distinguishing it from the hundreds of others that had been confiscated, intending to prevail on the book's literary merit as Penguin Books had done four years before in the trial of  Lady Chatterley's Lover.
