Ursula Le Guin on Lovecraft.

I really enjoy the Times Literary Supplement's "Then and Now" feature. One of the recent ones is Ursula Le Guin's 1976 review of Lyon Sprague de Camp's Lovecraft: "Lovecraft dangles like a rabbit from the jaws of his unconscious."

Of related interest: Brown Daily Herald on the real-life setting for Lovecraft's The Shunned House.
