Poetry. A SLEEPLESS MAN SITS UP IN BED, the third collection by the poet and translator Anthony Seidman, charts a cartography of the here and the beyond--from the fossils of trilobites to Aztec religious beliefs--and grounds itself in the political and artistic borderlands between the United States and Mexico. Drawing on the time the author spent living in Ciudad Juarez, this innovative collection converses with the great poets of the border region.
