Selections of Simic's work are available online at the Academy of American Poets and the Poetry Foundation websites. I highly recommend his Selected Early Poems, the prose poems in The World Doesn't End, all of his essays and memoirs, and his book about our beloved Joseph Cornell, Dime-Store Alchemy.
It's only appropriate to end with a poem:
by Charles Simic
This strange thing must have crept
Right out of hell.
It resembles a bird’s foot
Worn around the cannibal’s neck.
As you hold it in your hand,
As you stab with it into a piece of meat,
It is possible to imagine the rest of the bird:
Its head which like your fist
Is large, bald, beakless, and blind.
