A series of essays on Tolkien.
The commonest one was "the impact The Lord of the Rings had on my life and writing". A lot of them picked it up in the 60s or 70s when, really, there wasn't that much fantasy about. Terry Pratchett actually got pointed at Beowulf when he asked for more books like it -- fortunately he noticed books that had guys with helmets on theri covers and dived in. (That shelf was marked History, BTW.) One discussed Bored of the Rings and how it taught her the comic effect. One actually found "On Fairy Stories" the one with deep impact. Another's first reaction was how on earth can I keep on writing when the most amazing book has already been written.
Also discussion of his treatment of elves, analysis of his patterns, and a few other looks about.
