There was a thread on this list recently involving the development of a map that displays all libraries using Koha. David Friggens had developed a version using Google maps and data from lib-web-cats, but I think that it involved manually adding entries to the map. The map for ILS implementations is one example of a more extensive map API that I have created in lib-web-cats that I'm still in the process of documenting. I have created a new map facility in lib-web-cats that can be used to display such things as all libraries using Koha that are represented in lib-web-cats. It's still in draft form, but here is the map for Koha libraries: http://www.librarytechnology.org/map.pl?ILS=Koha Comments, suggestions, corrections, etc, definitely appreciated. I hope this is useful.
