O'Hara is from what's known as the New York School of Poets and you might like their other stuff: Dean Young, Kenneth Koch, John Ashbery, but don't jump in on it if you don't want. Also I may have thrown Dean Young in there without him really belonging but he fits in there in my head. I also think you might like Lawrence Ferlinghetti and I've been trying to find a good one to recommend to you. I quite liked his book "A Coney Island State of Mind" but my poet friends were more mixed on him. Retired Ballerinas, Central Park West I'm also insanely fond of Louise Gluck. However, I think she is most impressive when her poems are read in their book format, and less so singly. Here is my favorite Gluck - April "I wish what I wished you before, but harder" - Richard Wilbur, The Writer
