Unclean Lips: Jews, Obscenity, and American Culture by Josh Lambert
Buy this book at Amazon or for Kindle
Tells of the risks Jewish writers faced if they dabbled in obscenity. And they were serious. One place you never want to see your name is beside the words v. United States in a court document, yet that was far more likely for Roths, Ginsburgs, and Mishkins than for Smiths, Joneses, and Johnsons. In the 1930s, a stunning 90% of arrests for obscenity involved Jews. Free speech, in other words, was hardly free for these maverick writers and their publishers.
