Abstract: This article examines Edmond Jean-François Barbier’s invaluable account, in Chroniques de la Régence et du règne de Louis XV (1718-1763), of the publication and clandestine circulation of Jansenist literature, especially Nouvelles Ecclésiastiques, in the early eighteenth century. Barbier’s work recounts the strategies employed to draw the attention of the censor and the police away from the book.
