So is there also a Tolkien list???
I do not know of any Tolkien list - but it would be a very good idea. Some articles about Tolkien have mentions of Narnia and so come up on this list.
With these bio films about Lewis and Tolkien, I wonder how they will handle the sombre topic of the end of their friendship - there was a rift between them, which meant that at the time of Lewis’ death they had not spoken for years. The exact reasons for this are difficult for biographers to untangle.
