Expurgation is a form of censorship which involves purging anything deemed noxious or offensive, usually from an artistic work.
Bowdlerization is a pejorative term for the practice, particularly the expurgation of lewd material from books. The term derives from Thomas Bowdler's 1818 edition of William Shakespeare's plays, which he reworked in order to make them more suitable for women and children. He similarly edited Edward Gibbon's Decline and Fall of the Roman Empire.
A fig-leaf edition is such a bowdlerized text, deriving from the practice of covering the genitals of nudes in classical and Renaissance statues and paintings with fig leaves.
