Abstract
Location-based services have been around since 2000, but their popularity increased significantly with the launch of Foursquare and Gowalla in 2009. This column describes location-based services, examines Foursquare and Gowalla, and provides examples of libraries using location-based services to market library services and communicate with their users.
