I was googling for some literature on the Hindenburg Explosion when I came across NationMaster. It is a great encyclopedia site that is designed neatly. Tons of information (Can't say with surety if it is authentic though) and it is free! The chronology of events for all the years dating back to 1900 can be viewed by typing in http://www.nationmaster.com/encyclopedia/ followed by the year as http://www.nationmaster.com/encyclopedia/2004. Isn't that cool? The rollover text for images is also helpful!
