The Marteau collection of fictitious imprints is considered by scholars to be the best collection of books bearing the false imprint of “Pierre Marteau, Cologne,” a completely fictitious imprint invented by Dutch publishers for use on seventeenth and eighteenth century clandestinely published texts which, because of their forbidden content—politically radical, anti-Catholic, pornographic—ran the risk of being censured. Although initially limited to imprints of Pierre Marteau, the collection now embraces all identified fictitious imprints from any period and place.
Fictitious imprints in the Marteau collection have call numbers beginning with Z233.M3; a list of these titles can be retrieved with a call number search of this prefix in the online catalog.
