I am struck here by what is not being said:

“. . . Archives spokeswoman Susan Cooper said officials there “are confident that there aren’t any original documents missing in relation to this case.” She said in most cases, Mr. Berger was given photocopies to review, and that in any event officials have accounted for all originals to which he had access. ”

This does NOT say that the archive got back all the material that left with Sandy Berger. It just says the staff has all the material accounted for.

The staff were onto him, don’t forget. I’ve suspected from the start that they had made copies of whatever they let him see.
