Plazes.com now has Google Maps - Plazes is described from their website as "..a grassroots approach to location-aware interaction, using the local network you are connected to as location reference. Plazes allows you to share your location with the people you know and to discover people and plazes around you. It's the navigation system for your social life and it's absolutely free."

The unique bit is that not only do you get the library locations on the map [based on a a select radius around a city/town] but in the overlay you get to create a search of the library catalogue. I personally think this is prime for the UK public-info mapping contest being held by IdealGovernment.com(.)
