For those who might be interested, I have a new essay in print:
“Reluctantly Inspired: George MacDonald and the Genesis of J.R.R. Tolkien’s Smith of Wootton Major.” North Wind: A Journal of George MacDonald Studies 25 (2006): 113-20.
Unfortunately, the George MacDonald Society website hasn't been updated in some time, so I can't link you directly to the journal issue in question. But if you'd like to read it and don't have ready access to the journal in your local library, drop me a comment or an email, and I can send you a copy.
