My favorite list poem is Ted Berrigan's "Three Pages." It's ten things he does every day (play poker, drink beer, "lunch" [a noun here, not a verb], read, poems, hunker down, [accept? endure?] changes).
The Sackner Archive (of Miami) and UbuWeb. Two treasures in the world of concrete, sound, and visual poetries. They've come together now, as Matthew Abess has curated an anthology of sound recordings from Ruth and Marvin Sackner's collection and Kenny Goldsmith at Ubu has made digital space for them and added the list to Ubu's site. It's all semi-rare to rare, great and strange stuff.
