For a century, US insurance companies used Sanborn Fire Maps to decide the premiums customers would pay for fire insurance. These maps were designed to show the building materials used in each structure in 12,000 communities across 300,000 maps. While they have become obsolete, these maps are still useful for historians and urban designers, and anyone interested in lovely, original typography. Dive into the most artful Sanborn Fire Maps with this passion project collection.

This podcast examines how one organization reshaped the American public's relationship with recycling, asking why responsibility for a cleaner environment falls to individuals rather than to the companies that produce waste.
