Persuasive Maps is a collection of more than 800 maps collected by P.J. Mode housed at Cornell University library. This collection holds maps dating from the 1800s to the present day and covers various geographical areas of the world.
Persuasive Cartography seeks to communicate more than geographical information and intends to influence opinion or to send a particular message. Since maps represent a subject viewpoint, cartographers needed to decide what information to include or exclude.
Maps sit somewhere on the spectrum between science and art and subjectivity and objectivity. The maps of this collated collection are chosen because they communicate messages beyond geographical information. For instance, they illustrate a whole range of human concerns from religious, political, military, commercial, moral and social.
On May 3, 2016 P.J. Mode in a presentation to The Grolier Club of New York and New York Society, gave an interesting talk entitled “Deconstructing Persuasive Cartography”, in which he elaborated on the concept and idea of Persuasive maps and discussed different examples of maps from his collection.

Along with developments in technology and communications, the methodology of persuasive cartography has also developed. “The collection reflects a variety of persuasive tools: allegorical, satirical and pictorial mapping; selective inclusion or exclusion; unusual use of projections, color, graphics and text; and intentional deception.”
