Disputes in Exploration History: Creating the Caverio Planisphere, Mapping the Chicago Portage, and Exploring South American Rivers

We are pleased to present a new issue of TI , one that we find interesting and informative that we hope our readers will enjoy. We are delighted to include two engaging, illuminating, and well-researched articles, both of which advance our understanding by challenging conventional wisdom on important topics in exploration history. Additionally, we are pleased to include a stimulating and informative film review essay on a fascinating subject: rivers. Finally, we are happy to include a “Recent Literature in Discovery History” piece with interesting new titles after a two-year break (or last “Recent Literature” piece appeared in August 2020 ). As is typical, the issue is rounded out with our “Reviews” section that examines recent works. What follows is a preview of the engaging pieces in this issue of TI , which are discussed in the order they appear.
