“Literary Copernicus: The Cosmic Fiction of H.P. Lovecraft” is an online course this summer, from the Mythgard Institute. It runs 4th May – 24th July 2015. With a very cool teacher too, Amy H. Sturgis, though that’s balanced by the fact that the course costs $175 plus the cost of a copy of the Annotated Lovecraft. Presumably there are also student discussion forums and some written assignments, though that’s only my guess as there’s no mention of them.
