The Winter Journey (Georges Perec, 1979) led to a series of sequels by other members of the Oulipo in which transfictional operations are explained and justified. Each “journey” in the oulipian group is presented as a rewrite of the perecquian original taking into account to a lesser or greater degree the transfictional versions (that is to say the interval between Perec’s fiction and the transfiction concerned). In fact “the journey,” we will come to understand, is more like a sinuous itinerary, crossing and intertwining the perecquian library with the “oulipian library.”
