Do you know if Richard Siken plans on having his poetry published in another book? I don't mind reading on the internet but I much prefer curling up and reading poetry in paper-form.

His poems have occasionally been published in other books and magazines, but as far as I know there isn’t a specific book plan or anything.  He said something in an interview sort of relating to the topic:

I had the sense that I was expected to produce Crush 2—and there is no Crush 2, couldn’t possibly be aCrush 2 even if I was interested in attempting it—so I started to feel boxed in. But I was still feeling things and thinking things and my hands wanted something to do. So I got out my paints and squeezed the tubes, started pushing the color around without over-thinking it. I shut my mouth and opened my hand. After a while, I found myself thinking things, saying things, related to the paintings. My new poems started there.

Obviously he’s still writing, just not necessarily at a pace that will have another book coming out anytime soon, unfortunately.
