I have given up on universal sorting when I learned that dutch libraries 
sorting of author names depends on the country of origin of the author. 
So if Jan van Beek is dutch he will be sorted under B, while if he's 
belgian under V. I haven't checked what happens if the author emigrates, 
or changes nationality...
