It might be hard to wander around Milwaukee in 1910, unless you have a friend with a functioning time machine. Well, such a journey through time and space is almost possible with this fine collection from the University of Wisconsin-Milwaukee Library. The collection brings together the Sanborn Fire Maps from 1894 and 1910, and these documents are excellent historical resources for academics, geographers, urban planners, and those with a love of the built environment. Each map contains copious details on the construction materials of dwellings, sidewalk widths, and elevator locations. This collection is quite a pip, as it allows users to use Google Maps to wander around the city at their leisure, picking out details along the way. Visitors can use the "Browse" button to look through different sections of these maps, or they can just search for certain terms and locations.
