There’s 44 pages to it, each page hosting 50 books… so yeah, there’s a lot, especially of history, natural history, religion, and philosophy. But taking a look at the books classed as fantasy, of which there are 85, I see fantasy pioneers James Branch Cabell, L. Frank Baum (creator of Oz), pulp writer H. Rider Haggard, George MacDonald, Charles Kingsley (The Water Babies), Lord Dunsany, Edith Nesbit, and William Morris. All of these authors have been mentioned by Lewis scholars.
I was also right about Lewis being a fan of the Lovecraft Mythos, as was hinted at in The Silver Chair; one of the books was by Robert Bloch, Lovecraft’s longtime collaborator.
For Lewis’s post-1920s books, there are were a few surprises, like Jane Gaskell, Isak Dineson, Virginia Wolff (author of the gender-bending Orlando — whose titular character was portrayed by Tilda Swinton, the later White Witch!) and James Thurber.
Through the above, I found this paper on Disney’s film adaptation of Prince Caspian.
And also movie-related, this podcast on the failures of Disney’s The Voyage of the Dawn Treader movie.
