Mashup Idea

I'd like to be able to create a virtual mashup where by users could browse the library shelves virtually using a Google Maps-like interface. A customer would look up a book in the iPAC and then click on a link to see a Google-like-map of the library stacks where that book is shelved. The customer could then zoom in to see what other books are shelved nearby, and could zoom out if needed to see where in the library the book is located. How to do this? I have no idea.
