title: Powder diffraction: what's in a name?
abstract: The development of powder diffraction is briefly described; the extent of this development from studies of metals to protein crystal structures shows that powder diffraction is at the cutting edge of crystallography. A new name `polycrystallography' is proposed for these endeavours.
