They had another Conference a couple of years back - 'Landscapes with Angels' - about fantasy literature, with a focus on Tolkien & Chesterton & the talks from that have been published as a special edition of the Chesterton Review, so I'm assuming the same will occur with this one. Its available as a single issue here
http://www.isi.org/journals/chesterton_review.html
And for anyone who didn't make it to Birmingham last year the Tolkien Society are due to publish the talks from that either later this year or next.
