Example:  The Sanborn® Fire Insurance Map of Muncie, Indiana, from 1883 includes numerous blacksmiths, liveries, feed stores, carriage shops, and harness and leather shops.  Nearly every dwelling and most businesses also had a stable at that time.  Students of history could research a specific area of the map on the subsequent Sanborn maps of Muncie—up to 1911—to analyze the changes in these equine (horse-related) structures and businesses.  The Sanborn maps of Muncie from 1954 available in Archives and Special Collections could be used to supplement this learning project.
