Here's a neat idea. Ender, Duke of URL has started putting together a Google Map of of libraries in Maricopa County, Arizona. He writes "If anyone has any familiarity with block loading, so that my points could be made to dynamically load in a larger set of cooridinates, or to include uris/urls and links in my text-boxes, I'd appreciate the help. I've been told that after loading up several hundred points it starts to crawl, and you can't put more than a thousand in one map. It'd be cool to contribute towards a nation-wide map of libraries...
