Lena Denis, Geospatial Data, GIS and Maps Librarian at the Johns Hopkins Sheridan Libraries, discusses "The Foundation and the Gateway: What Maps Show and Hide about Baltimore and American History," a virtual talk delivered March 26, 2021.

To our modern eyes, maps are a straightforward abstraction of geographic space and how to navigate within it. However, the history of mapmaking as we know it is deeply entwined with the rise and fall of empires, religious and territorial wars, and the ever-present quest to count, house, and tax populations. Join Hopkins' maps librarian and alumna Lena Denis for a Map Collection tour of Baltimore - a city where maps reveal all of these stories and many more - featuring important selections from the university's collection of historical Baltimore maps.
