True, 90% of my professional library is English. But this does not mean that the last 10% are not noteworthy. So it would be nice if you searched not just amazon**.com** for books but all of amazon (iE. Amazon**.co.uk**, amanzon**.deamanzon.fr**).
I take it that all amazon sites have the same web service interface so it would just be a matter a list to sited to search.
