Revisiting this post briefly (and I so rarely do come back to these things), "the bloke from the lecture" has posted his own blog entry about that Monday lecture here. Besides a very artistic looking photo of Alan Dix, the post includes links for the slides used in the lecture and the Tallis website.
I'm not going to post any more comment on the lecture, but I shall include a list of the books mentioned (or at least those mentioned in the part I managed to attend). I've added them to my BookMooch wishlist so maybe I'll acquire some of them one day.
