Single purpose API
InfoChimps, those enterprising primates, have another incredibly interesting dataset to offer up to the world: 60,000+ UFO Sightings. And you thought that they didn’t exist! Now you’re going to have to apologize to the believers that you mocked because this dataset has come to set the record straight. Aliens exist and the evidence is the InfoChimps Datasets API, which makes searchable every documented sighting.
The Open Library is a project of the non-profit Internet Archive, whose long-term goal is to present "one web page for every book ever published."

Wikimapia is a web service that allows users to edit information on a world map in a wiki format. Users of the site can add places, edit them, and get the information previous users have entered. The info there is currently pretty sparse, but the service is rather new. The company also recently released a Wikimapia API that supports getting information from the web service.
