By Ed Sanders. The author, a "poet, political activist and member of the folk-rock pranksters The Fugs," has also written "verse biographies" of Chekhov and Ginsberg, but don't hold that against him. This edition is “updated with 5 chilling new chapters” and is from 1990.
The paperback is a bit frumpy -- foxing to the page edges, tanning inside the covers, toning to an extent inside; edgewear and a cracked spine -- but this reading copy will get the job done.
