This time I am paying a bit more attention to some of the legal history surrounding the novel, which as is well known was banned for obscenity in the United States in 1921, and unbanned in 1933. The immediate episode that provoked the ban was episode 13 ("Nausicaa"), which was printed in pieces by the journal The Little Review. The editors of that journal, Jane Heap and Margaret Anderson, were the ones prosecuted in the initial trial, after a lawyer in New York complained about it. That lawyer stated that his daughter had read and been shocked by "Nausicaa" after receiving The Little Review in the mail. The figure of the innocent daughter, "the young girl" reader who might be corrupted by Ulysses became a key rhetorical figure in the to-and-fro over the novel that followed.
1. The documents related to the original trial are not easy to come by online. The best essay I have seen on the subject is a Washington University Law Review essay by Stephen Gillers that describes the history of the trial (as well as its precedents) in great detail. The key discussion related to Ulysses begins around p. 250.
2. One document that is online, but not in a very good form, is Jane Heap's initial printed defense of the novel, and of the Nausicaa episode in particular, which she printed in The Little Review in the fall of 1920 (before the first trial was decided). That essay is called "Art and the Law," and it can be found in an Archive.org uncorrected scan of several issues of the magazine here.
I have gone through that scanned version and corrected the mistakes caused by OCR. Since the document is, I believe, out of copyright, I am posting the corrected version of the essay here as a service to any colleagues who might find it useful:
