We're going to go behind the scenes to look at a map that didn't make it into the exhibition.

I'm Garrett Dash Nelson, the Curator of Maps & Director of Geographic scholarship at the Leventhal Map & Education Center at the Boston Public Library.

In Bending Lines, we're taking a look at a big question: how are truth and belief shaped by maps and other visual forms of data? Some maps are obviously trying to distort the truth, make an argument, or sell you something, and we're showing some of our most extraordinary maps like this in the exhibition. Whether it's a giant octopus in the place of Russia, or a map advertising cheap land in the suburbs, these kinds of maps are clearly playing fast and loose with persuasion and emotion. But one of the key arguments we make in Bending Lines is that all forms of visual evidence make arguments in some way or another. Every map has to simplify the world, and make choices about how to represent the complexity of reality. Even a scientific-looking map produced from a sophisticated data source will still bear the traces of the creator's assumptions and biases.

On Earth 2, we'd be welcoming you right now to our Map Gallery in the Boston Public Library's Central branch in Copley Square to see Bending Lines in person. Instead, today marks the launch of our digital-first version of Bending Lines. It's more than just a list of collections objects—we've created an entire immersive web publication, with more information about the maps and more interactive content than we could ever squeeze into our physical gallery. You'll find the link to the digital exhibition below and on our website.

Now, I'd like to welcome a really special guest who will be talking with us about the maps she created for this exhibition.

VI. Other Maps in the Collection (10 minutes)

  1. Choropleth-esque map of Protestants and Catholics - uses deliberate cutpoints, with red showing Catholic-majority counties inside the proposed Ulster, to make its point
  2. 1980s Radioactive Map - uses line width and separation to make routes seem much wider than reality, seemingly putting more of the country at risk from
