Emmet Rensin, a sophomore at the University of Chicago when he's not in Tarzana, will guest on KPCC's "Patt Morrison" at 1:30 p.m. to talk about "Twitterature: The World's Greatest Books in Twenty Tweets or Less," the book he and a friend wrote. It renders the classics of literature in 140-character Twitter tweets. Did I mention that he's the son of LA Observed contributor David Rensin?
