sentences:  The Bastille was a preferred location for holding prisoners who needed extensive questioning or where a case required the analysis of extensive documents.The Bastille was also used to store the Parisian police archives; public order equipment such as chains and flags; and illegal goods, seized by order of the crown using a version of the "lettre de cachet", such as banned books and illicit printing presses.Throughout this period, but particularly in the middle of the 18th century, the Bastille was used by the police to suppress the trade in illegal and seditious books in France.
