I was gonna be all clever and mean and just link you a part from de Sade's work. I read some of that as a teenager, because it was fun to read hardcore BDSM porn between classes and be complimented for "reading such a thick book".
Anyway, turns out there never has been an (uncensored) english publication of some of de Sade's texts. Apparently it's a bit too strong for delicate anglo-saxon minds:
There is standard edition of this text in hardcover, having passed into the public domain. The text itself is often incorporated into collections of de Sade's work.
A censored English translation of Justine was issued in the US by the Risus Press in the early 1930s, and went through many reprintings. The first unexpurgated English translation of Justine (by 'Pieralessandro Casavini', a pseudonym for Austryn Wainhouse) was published by the Olympia Press in 1953. Wainhouse later revised this translation for publication in the United States by Grove Press (1965). Other modern translated versions in print, notably the Wordsworth edition, are abridged and heavily censored.
The final 1797 version La Nouvelle Justine has never been published in English translation, although it was published in French in the permissive conditions of the late 1960s, as part of two rival limited-editions of the definitive collected works of de Sade: Jean-Jacques Pauvert's Oeuvres completes de Sade (1968, 30 volumes) and Cercle du Livre Precieux's Oeuvres completes du Marquis de Sade: editions definitive (1967, 16 volumes).
