Sook amazon and ajax

The next idea I am working on is  to try is to use the power of amazon to look for material.  Specifically books. What I am hearing from staff and patrons that they are using amazon to get the details on the book they want and then using that information to look up our catalog. Well why not automate that process. I have just started working on a Google like interface where you can to a search amazon if you are not certain of the title or author and it will give you results. I plan on using ajax to dynamically go out and hit the catalog and see if we have that material.
