Modern reference outlines locate the historical thematic data. The underlying rights/protest classifications remain unchanged.

Germany uses dated East/West source extents together with a Berlin reference; Czechoslovakia, Yugoslavia and the Soviet Union use reviewed historical extents. For Czechoslovakia and the Soviet Union, the 1953–68 references are retained where later Cliopatria records show military occupation rather than treaty-party territory.
