Sil or HoME?

I will not comment on what seems to be the circular logic and self-congratulatory nature of the final entry, except to say that as far as I'm concerned, Tolkien did not, despite the yearnings of some (even many), write a new bible.

Well, at least he did not write The Bible anew...
But as a background-work for The Hobbit, and even more, The Lord of the Rings, his work with The Silmarillion certainly works as writing a sort of bible, IMO.

The Adventures of Tom Bombadil was published in 1962 and The Road Goes Ever On in 1967.

Yes, and IMO, both are sorts of excerpts of The Lord of the Rings...
