What Books That Tolkien Read Have You Read?

[Maiden_of Harad]

...Aside from his own, that is.
And if so, can you detect their influence, if any, on him?
As for me, I've read:
Beowulf- prahaps the burial mound with treasure guarded by a cruel guardian.
I don't know which George Macdonald books he read, but I've read Lilleth, The Princess and the Goblin, and The Light Princess and Other Stories. Prahaps the influence here was on his elves, who, like some of the fairies in these books, are old yet young and beautiful.
Alice In Wonderland- I can't detect any influence here.
Since he objected to Aslan, I'm sure he read The Chronicles of Narnia, which I've read or heard on audiobook.
That's all I can think of for now.

 

[Prince of Cats]

I've read his translations of poems in Sir Gawain and the Green Knight and his adaptation of the Edda in Sigurd & Gudrun, both of which it's not hard though interesting to draw parallels with various instances in his own writings
