Julien Gracq's manuscripts at the BnF

From a recent Chroniques de la Bibliothèque nationale de France , we learn that Julien Gracq's (1910-2007) papers have been deposited in the BnF, rue de Richelieu collection. The approximately 15,000 manuscript pages include the drafts and workbooks of his entire oeuvre, although seeing some of them will require a 20 year wait, at the request of the author.
