Any devoted Pynchon reader knows that “The Secret Integration” originally appeared in The Saturday Evening Post and that portions of The Crying of Lot 49 were first serialized in Esquire and Cavalier. But few readers stop to ask what it meant for Pynchon, already a reclusive figure, to publish in these popular magazines during the mid-1960s, or how we might understand these texts today after taking into account their original sites of publication. “The Secret Integration” in the Post or the excerpt of Lot 49 in Esquire produce different meanings in these different contexts, meanings that disappear when reading the later versions alone.
