Bibliothèque bleue describes a period of prolific chapbook publishing in France between 1602 and 1830. These books were bound inexpensively in blue paper, leading to their name. This business allowed for a wide distribution of short and sensationalist grimoires, which take a much more diabolical bent than their source material, presumably for the lurid appeal of magic that involves human skulls and animal sacrifice.
