Google Books Viewability API

Google has released a new API that supports links to volumes in Google Book Search. Web developers can use the Books Viewability API to quickly find out a book's viewability on Google Book Search and, in an automated fashion, embed a link to that book in Google Book Search on their own sites.

We'd already created our own service for our Virgo catalog for digitized UVA volumes that are available as full-text in GBS. We were thinking about how we'd potentially port that to Blacklight -- now we can look at the API in addition to what we'd done ourselves.
