Digital maps at the Osher Map Library show promise and perils of digitization.

Noted: When all that context drops out, you’re left with the mere content of the map, which can make it harder to understand in truly historical terms. Jonathan Senchyne, director of the Center for the History of Print and Digital Culture at the University of Wisconsin–Madison (and a graduate school colleague of mine), says that this can sand down the historical texture of an object. “There’s always a temptation to think about something that’s been [digitized] in presentist terms,” Senchyne told me. In other words, it’s challenging to break free from our own ways of understanding and moving through space when we only access the past through a digital lens.
