Preliminary remark: The contents of the present repertory are files of the Royal Cabinet, which were handed over to the State Archives with two summary indexes after the Revolution. Since these lists proved to be insufficient, a new, extensive repertory was created. The original collection has been preserved in its entirety, with the exception of a few insignificant fascicles, not listed in the old registers, which have been excreted; they have remained essentially in their original order; only in a few places has it been modified in favour of a more summarised or systematic classification.
