Found a possibly interesting one, either because it's not clear why it was ever classified, or perhaps because it has some previously undisclosed diplomatic procedures. It describes the 201 dossier system, and circumstances under which one is automatically opened, categorized by known persons of various other regions and states.

Anyone have a sense of whether any of this is new?
