Trans-Atlantic Slave Trade...

This site is interesting on several levels: as a demonstration of accessible data mining, as a tool for quantative history study, and as a means for anybody to informally learn a lot more fact-based history (a commodity in amazingly short supply!).

The screenshot at right (click to enlarge) shows one of my own explorations: I wanted to know where slaves actually went.  Answer: the vast majority went to the Caribbean and to South America – not North America.  Prior to seeing these numerical data, I'd known that many slaves went to the Caribbean – but I did not know that such an overwhelming majority went there, nor did I know that so many went to South America.

There is much else to learn at that site...
