Cornell University Library has been home to the P. J. Mode Collection of Persuasive Cartography since 2014, and that collection is very much available online. Today, though, a new exhibition of maps from that collection opens at the Carl A. Kroch Library’s Hirshland Exhibition Gallery. Latitude: Persuasive Cartography runs until 21 February 2020.
Cornell isn’t the only repository of maps intended to persuade or propagandize. The Library of Congress acquired a collection of 180 such maps, focusing on war and propaganda in the first half of the 20th century, in 2016.
