John, The Biodiversity Heritage Library has geocoded our books and journals based on LCSH geographic headings (not based on geonames in full text). http://www.biodiversitylibrary.org/browse/map Our data is available via APIs and datasets and while we do store the lat/long info we acquire from Google Maps api we are not allowed to share it within our datasets because it would violate Microsoft's Terms of Service. Here is a link to a presentation Chris Freeland did recently on our geocoding http://www.slideshare.net/chrisfreeland/built-works-registry-geocoding-biodiversity-heritage-library The end of the presentation links to a 2008 article in code4lib that explains more of the technical details.
