JSON Books API : Standard library

From WikiThing

Note: Needless to say, this isn't a live copy of the code. But we'll watch out for changes and push them live as warranted. When editing, try to add to the code or improve how the code works, not change what it does. Although the whole API is very much beta, we should move to stable functionality whenever possible.
