Very interesting reference found in Dora Zang’s Is There a Future for Literary Studies? Zang mentions Rachel Sagner Buurma and Laura Heffernan’s The Teaching Archive: A New History for Literary Study (The University of Chicago Press, 2020). I quote:
Examining materials ranging from T.S. Eliot’s lecture notes from his classes at an extension school for working adults to Simon Ortiz’s efforts to establish a Native American-studies curriculum at the College of Marin, Buurma and Heffernan show that many of the key methodological developments in literary studies over the 20th century have developed in and through the classroom. This startling claim counters the familiar idea that the discipline’s theories and practices are pioneered by scholars at a handful of elite institutions “only later to ‘trickle down,’” as Buurma and Heffernan put it, “to non-elite institutions, students, and teachers.” It also challenges classic disciplinary histories like those by Gerald Graff and John Guillory, which characterize the history of literary studies as a series of “method wars,” whether between belletrists and philologists at the turn of the 20th century, or formalists and historicists towards that century’s end.
