I recently visited the Boston Public Library and was fortunate to encounter the Norman B. Leventhal Map & Education Center which was presenting a huge exhibit titled “Transforming America: Mapping the 19th Century.” The exhibit is being staged in two parts. The first is called The United States Expands Westward and will be on display until November 2019. Part Two is called “Homesteads to Modern Cities, 1862-1900″ and will be on display Nov. 12, 2019 until May 10, 2020. If you are in Boston during these times I highly recommend stopping in to see all the maps they have collected and curated for this exhibit, it’s extraordinary! The exhibit is free and open to the public. Be sure to allow at least an hour to read and examine all of the displays!
