Ray's Last Composition?

According to his biographer Sam Weller, the last thing Ray Bradbury wrote for publication prior to his death was "The Book and the Butterfly" It's a short essay written as the introduction to The Best Nonrequired Reading 2012. How does Sam know this? Simple: Ray dictated it to him in April and they worked on the revisions in May, shortly before Ray passed away.
