== Use of the serial comma? == 

 A look at the serial comma would suggest that Oxford spelling, rather that used by Oxford University Press, would prefer to use the American-style serial comma, that is in a list item: 

   Item 1, Item 2, Item 3, and Item 4 

 Whereas the standard British English being without a comma before the last item, i.e.: 

   Item 1, Item 2, Item3 and Item 4
