A fascinating website called The Full Wiki has recently been brought to our attention.
The site contains an excellent mapping tool that allows users to visualise the locations of all places and events mentioned in any wikipedia article.
The entry for World War II for example, brings up a detailed map. Clicking on any point will bring up the snippet of text in the Wikipedia article that mentions that specific place. Needless to say, this is a useful tool for uncovering the not only the places mentioned in any article, but also the silences and omissions.
We should point out a curious anomaly for the map of the article on monkeys. The only location shown is in downtown Washington DC. We won't ask why.
