Copies of the journal began to appear last month, but it has taken a while for it to make its way across the pond. You can order directly from the publisher, Kent State University Press, or from Amazon, using the links below.
Here's the official flyer which explains what the issue is about. I wrote the original copy for the flyer. I also wrote the introduction to the issue, and the essay which concludes the issue. Other contributors include Jon Eller (author of Becoming Ray Bradbury), Bill Touponce (co-author with Jon of Ray Bradbury: the Life of Fiction), and film scholar Joseph McBride (author of Steven Spielberg: a Biography and Whatever Happened to Orson Welles, among many others).
