Field notes
The map uses filled lights for Steel locals and open rings for Auto locals; clustered locals make a town's glow brighter. Its roll links each local to a plant, town, and record, while warning that local numbers and locations shifted and that mapped plant placements are approximate. The project credits D. Willems of Lake County, Indiana, and uses public-domain Library of Congress photographs labeled by place, work, and year.
