Meta Search for Inside the Book Searches

Over the last year or so, several search engines have been released that let you search inside books (Google Books, Amazon Search Inside/A9 & MSN Live Book Search). But there has never been a way, until now, to search them all simultaneously.
Developer Kokogiak notes that there are some big differences in the type of books available on each system. “It’s been interesting to see the quantity/quality differences between the 3 in trying several searches. Results for “ajax”, for instance – Amazon is all current programming books, Google is a mix of classic mythology and programming, and MSN is all classic mythology.”
