Poetry. Nonfiction. Poetics. The collection of seventeen writers is an investigation of the form of extended poem, series, sequence, or the idea of the "book"; an entire book of Larry Eigner's, Anything on Its Side, is included, as well as an entire book by Alice Notley: Parts of a Wedding. The collection contains commentary on the writings of those included, or poets writing commentary either as poem or essay on their own work; there are essays by Robert Grenier, Nathaniel Mackey, Lyn Hejiinian, Michael Palmer, Alan Davies, Charles Bernstein, and Abigail Child.
