Émile, ou De l'éducation
Jean-Jacques Rousseau · Nicolas-Bonaventure Duchesne, Paris — issued under false Néaulme imprints ('A Amsterdam, Chez Jean Neaulme' on the duodecimo; 'A La Haye, Chez Jean Néaulme' on the octavo) · 1762
The octavo is normally found with all four cancels; copies retaining the cancellanda (the original uncancelled leaves) are exceedingly rare — McEachern located a single copy, at Stuttgart, holding the two cancellanda of volume I, and none at all for volume II. McEachern records that the duodecimo sheets were set and printed first and then re-imposed for printing in octavo, but that the octavo appears to have been issued first, and states that the question of the order of printing 'has not yet been resolved to everyone's satisfaction' — so no confident 12mo-versus-8vo precedence should be asserted
