The French Archives Nationales contain 252 miles of documents, measured according to shelves loaded with boxes full of manuscripts, and they do not include material related to defense, foreign affairs, and overseas territories. France's one hundred provincial archives contain far more -- about 1,753 miles. Still more can be found in municipal archives, various university archives, and private collections. Most of it has never been read, much less scanned.
