I came across this quote today, from Molly McQuade's Stealing Glimpses:
"Poetry is slow. Poetry forces you to slow down how you breathe, how you think..."
-- Michael Wiegers, managing editor of Copper Canyon Press.
Incidentally, I've never been disappointed in a Copper Canyon book. Founded by Sam Hamill, one of my favorite poets, they have published W.S. Merwin, JIm Harrison, Kenneth Rexroth, Arthur Sze, among others. They have also produced various volumes of translations from the Chinese, including Hamill's own.
