GeoURL (http://geourl.org) allows authors to locate their documents in the physical world rather than the virtual world. Instead of visiting an arbitrary and artificial "neighborhood" defined by a search engine listing, viewers find documents that exist nearby in their own real neighborhood -- or in another neighborhood they'd like to visit.

GeoURL provides geographical markup and a distance-based search engine to enable people to find what has been written for and about the nearby world. Thousands of sites in dozens of countries have participated in this project, helping to discover the spatial mapping between cyberspace and the real world.

Schachter discusses the implementation of GeoURL, including the problems and pitfalls. Interesting uses others have made of the system and how geographic markup has influenced online communities will also be covered.
