An interesting site that I've missed until today: EyeWitness, "history through the eyes of those who lived it." I haven't had a lot of time to explore it yet and only read of a few events in which I have a particular interest: The San Francisco Earthquake, 1906, The British Burn Washington, DC, 1814, The Destruction of Pompeii, 79 AD, and Doomed Expedition to the South Pole, 1912.
