While in the Ninth Circuit courthouse in San Francisco last month to argue an appeal, I bumped into the court's small library exhibit entitled "Locked Out: A Sampling of Books Banned in U.S. Prisons." Its list of books that have been banned in one or more prisons includes James Joyce's "Ulysses," D.H. Lawrence's "Lady Chatterley's Lover," and the Bible. The Supermax federal prison in Florence, Colorado banned president Obama's "Audacity of Hope" and "Dreams from my Father." The photo below lists the passages the Warden deemed "potentially detrimental to national security." The ban was ultimately rescinded.
