Here's an interesting (audio) interview with Brad Gooch, author of the just-published Flannery: A Life of Flannery O'Connor. His interview, which isn't long, provides an excellent introduction to O'Connor (1925-1954) whose popularity seems to grow year by year. Readers of O'Connor are well aware of her richly informative collected letters (The Habit of Being) mentioned by Gooch. Gooch tells us that O'Connor wrote 3 hours each morning and generally wrote three to five letters a day, in addition to caring for 39 peacocks! She died of Lupus at age 39.
Recently I stumbled upon two online (video) lectures 
given by Yale Professor Amy Hungerford
on O'Connor's novel Wise Blood (available here and here). They compose part of Hungerford's Yale class on "The American Novel Since 1945" which covers in addition to Flannery O'Connor, Richard Wright, Vladimir Nabokov, Jack Kerouac, J. D. Salinger, Thomas Pynchon, John
Barth, Maxine Hong Kingston, Toni Morrison, Marilynne Robinson, Cormac
McCarthy, Philip Roth and Edward P. Jones. All her lectures are online and free.
