Have you ever thought about how much you can learn from a map? We have 1700 of them dating from 1720 to 2000. Our researchers are drawn to the ones dealing with the Civil War, topographical maps issued by the U. S. Geological Survey, and the Sanborn maps of Kentucky cities. The rarest ones in the collection are early river charts of the Green River, a number of hand-drawn maps, and those of Dutch cartographer Herman Moll, whose maps were published in England in the 1720s. We even have two maps of planned frontier communities that never developed. Compare our national and state highway maps to see the amazing development of automobile routes during the twentieth century.
