Ed‘s comment on rephotography in my last post reminded me of Chris Perridas’ blog, H.P. Lovecraft & His Legacy. I’ve been following it for quite awhile, and during that time, Perridas has unflaggingly posted a photo, letter, article, or some other piece of Lovecraftiana every day. While stopping by, be sure to check out some of his other blogs, particularly the Antiquarian Weird Tales one.
For further Lovecraftian research, you may want to consult the Fiction Mags site for a very thorough bibliography that gives the original publication information for each story or the Miskatonic University site, which hosts, among many other things, scans of every Weird Tales cover with accompanying tables of contents. The H.P. Lovecraft Archive also contains research material and bibliographies for each story and poem, and to read the original stories, check out Miskatonic U. or Dagonbytes.
