Killing Time: Life in the Arkansas Penitentiary by Bruce Jackson, Cornell University Press, Ithaca, New York, 1977. I’m really happy to have found a copy of this book today. As an undergrad, I was a visiting artist at Western Penitentiary in Pittsburgh (no longer open) and during that time I was particularly obsessed with this book. I’m sure I checked it out of the library at Carnegie Mellon at least several times. Killing Time remains a powerful look at prison life with many keenly observed and haunting photos.
