Happy to share. I can't post a poem for which I don't own usage rights. Hugo and Baudelaire wrote in French, most English translations are recent and thus have active copyrights, as do Ashbery's and Kizer's poems. As for websites who have published pantoums, I assume that this website has the same policy any good website has: don't link to other sites without their permission.

Here's how to find a pantoum worth reading: the following search terms yielded good results for me on Google. If you follow one or two of the resulting links, you'll find an example by Hugo. I liked the site by Greg Barta.

Good hunting.
