I have a lot of them, and they change regularly. I've just ordered Jim Simmerman's last book of poems from Amazon. He died at age 52 or so in 2006. Richard Hugo is another facorite. Louis Simpson, A.R.Ammons, Ranier Maria Rilke in the Mitchel translation, John Berryman's Dream Songs, Robert Lowell"s Life Studies, Kenneth Koch, Donald Justice is a sort of Poet's poet, Albert Goldbarth is wild and prolific with a zany side to him that's very endearing, Jane Shore is very Level headed and focused of family and relationships, Maura Stanton has a real depth an penetration and an essential eye for the vital detail, Mekeel MacBride has an enchanting lyric gift. I could go on for a long time, but those are the folks that are foremost for me at the moment, all of them moderns. I figure that any good anthology would give you the basic classic folks.
My best, Bob Kaven
