Library Thing

Similar to the older BiblioPhil and slightly older ReaderĂ‚Â², Library Thing does the social-book-(self-proclaimed)Flickr style tagging-organization. Right now, you can enter 200 books for free, but their beta-special lifetime membership is only $10 . As much as all of this photo tagging is popular and interesting, I tend to get a headache from all of it and am not completely sold on it yet.

Map Radius

Other than sites that offer a zip/postal code radius within so many miles, here is a site that actually outlines the geography covered by the code- very useful for cities, especially NYC. It also allows multiple queries on 1 map as well. This only works for the U.S. though.

UPDATE: Not sure of the Max # of requests but it stops allowing requests at some point and tells you to come back in 2 hrs. It may be doing this via the IP since I cleared cache, cookies, history, etc and still received the same message.
