Some of my favorite poets are Harvard poets: Delmore Schwartz, Wallace Stevens, and E.E. Cummings. So, I somehow stumbled upon a link that lead me to Harvard's Woodberry Poetry Room on-line.
What a treasure trove this turned out to be! Of course, it seems natural that well-known poets such as Elizabeth Bishop, Seamus Heaney, and Allen Ginsberg eventually find themselves addressing an audience at Harvard whether they were once immatriculated or not.
