This essay is one part documentation and one part provocation, with a simple goal: to acknowledge the agency of the literary agent. There is no figure more significant to contemporary literary production and less studied by scholars than the agent. Drawing on ethnographic interviews conducted with 28 literary agents over the course of four years, I argue that agents shape the form and content of contemporary fiction by acting as administrators of the logic of the marketplace, conditioning their clients to write in and for the international multimedia conglomerates known as the Big Four. I take the agent’s list to be one of the central organizing heuristics of the contemporary literary field and read the list of one agent, Nicole Aragi, to examine what I call “corporate taste”: personal aesthetic judgments carefully calibrated to anticipate and respond to the demands of publishing conglomerates.
