The thirty-sixth History Carnival is up at "Clews: The Historic True Crime Blog". I particularly want to emphasize that you should go and see, because Laura James managed to put together a good carnival in the absence of any nominations.
P.S. Oh, and I don't know how I could have forgotten to mention it (apparently I need to get back into the habit of paying more attention to carnivals again), but the newest edition of Carnivalesque is also up. It's an ancient/medieval edition at "Xoom". I especially liked this post on sixth-century Chinese essay writing at "Frog in a Well". This discussion of chryselephantine was also interesting; although (admittedly) I mention it in part because I've always liked the word 'chryselephantine'.
