Linking to Google Books Content in an Ancient Geographic Way

I'm very interested in finding ways through Pleiades and other ISAW digital projects to support the efforts of Leif, Elton and Eric on the "Google Ancient Places (GAP): Discovering historic geographical entities in the Google Books corpus" project. In particular, I'd hope we can integrate this into the web interfaces for our projects:

ECS will work on a Web Service and Web Widget [that] will make it possible for Webmasters to add links to the ancient texts [in Google Books] within their websites, enabling the public and researchers to search for them easily.
