My dear friend Judith Roitman reminded me I left out an important resource for the Poetry Publishing Basics post. I quote her here:
"State University of New York-Buffalo's Electronic Poetry Center, http://epc.buffalo.edu/, has generous samplings of hundreds and hundreds of poets, and some interesting links, including one to PennSounds MP3 files from lots and lots of poets (although not hundreds), including Ezra Pound, Charles Reznikoff, John Yau, Alice Notley, Jorie Graham, Jack Spicer, Ted Berrigan... In the C's and D's are John Cage, Paul Celan, Gregory Corso, Robert Creeley, HD (under her full name, Hilda Doolittle), Paul Laurence Dunbar, Robert Duncan...."
