Annotations in a copy of Finnegans Wake (illustration of this article.)
I recently did a blog post on correspondence by Robert Anton Wilson, to Hugh Kenner, on Ezra Pound, that's available at the Harry Ransom Center at the University of Texas campus in Austin.
PQ has now done a blog post that everyone reading this blog will want to take a few minutes to read, about the Austin, Texas, Finnegans Wake reading group taking a special tour of James Joyce artifacts at the Ransom Center. The visit was so inspiring, it launched a book project. And there's a bit of audio of Robert Anton Wilson reading from the novel.
