Union of International Associations Databases

This is quite something, possibly. What with the confusing interface and the sheer mountains of information here it's hard to tell exactly whether this is any use. However, it's still impressive, and great to browse around. A selection of large databases (some of which are free to use after registering), containing all sorts of odd stuff about the world. Try selecting the 'Word Problems-Issues' database and searching for something like 'future.' Then just browse among related issues and get horribly, totally lost. (via Futurist Update)
