Billy Collins' web site includes a link to free audio downloads.
Videos, I think they're flash videos, of something like 12 of Billy Collins' poems are at the Billy Collins--Action Poet web site.
Quickmuse is an interesting site. Poets are asked to compose a poem in 15 minutes or under in response to a prompt. As the poet composes, key strokes are collected. On this site you can watch those keystrokes appear. It's almost like sitting beside Robert Pinsky as he writes. Click on their archive button, and you will see that plenty of notable poets have played the quickmuse "game." I kind of like Matthew Rohrer's rambling poem. Quickmuse asked Rohrer to write in response to Bill Zavatsky's poem "Imaginary Brother."
Born Magazine is also worth exploring. Click on Enter Born Magazine once you're in.
This is a link to the Council of Literary Magazines and Presses. Their Directory holds links to the websites of all of their members. These websites contain submission info. After you click on the word "Directory" right here, or in the previous sentence, the index page will appear. Click on the words "All Members," and the links will appear.
