Aerial photographs of Minneapolis from the 1930s to the 1980s are coming to the University of Minnesota’s Borchert Map Library.

The photographs, Minnpost reported, were taken by airplanes every 10 or so years. Though this practice reportedly started in Minneapolis in 1922, only photographs from 1938 are still in the collection. They used to be held by the city, who provided them to construction companies who wanted to see what the property had looked like years before.

Now, a lot of that information is available elsewhere.  

At the University, the maps will be stored, digitized and made available to the public. Already, an app on the University of Minnesota Libraries website provides access to more than 113,000 aerial photographs of Minnesota and parts of Wisconsin.
