From my personal point of view, as a student of the history of fantasy and Tolkien's role in the creation of fantasy as a modern literary genre, the most interesting point was Kilby's revealing that one of the books Tolkien loaned him to read as preparation for working on THE SILMARILLION was Lord Dunsany's THE BOOK OF WONDER . One discovery that was new to me, not having been mentioned in the lecture itself but jotted on one draft, was learning that Tolkien also recommended Sheila Kaye-Smith's THE CHALLENGE TO SIRIUS  as "[the] best novel of the US Civil War". I don't know of any previous evidence that Tolkien knew Kaye-Smith's work; while largely forgotten today (aside from having been mocked by Stella Gibbons' COLD COMFORT FARM) she was famous in her own time both as one of Hardy's heirs and for a famous conversion to Catholicism in 1929 along with her husband (hitherto an Anglican priest).
Quite aside from my own interest in this volume from my own contribution, this issue has much else of interest in it. The lead article prints for the first time what its editor argues is the only part ever written down of Tolkien & Lewis's erstwhile collaboration, LANGUAGE AND HUMAN NATURE. There's also a short biography of Lucy Barfield and two Owen Barfield poems (one never before published)and a memoir of Lewis at Cambridge. So, all in all, a good issue; I'm looking forward to reading the other pieces.
