Bob McKinnon, host of the podcast Attribution, speaks with Maureen Corrigan, book critic for NPR’s Fresh Air and the Nicky and Jamie Grant Distinguished Professor of the Practice in Literary Criticism at Georgetown University. Corrigan’s book “So We Read On: How The Great Gatsby Came To Be and Why It Endures” is the focus of their conversation. They also speak about what “The Great Gatsby,” which was set on the prosperous Long Island of 1922, can still teach us about class in America today.
