Due to a computer loss, Excel spreadsheets for the maps dealing with the nineteenth century, Pennsylvania Gazette, and “frontier versus frontiers” that appear in Frontier Country are unavailable. Original copies of the graphs and tables in Word format, which include data, are available here, but do not provide the same ability to manipulate data as Excel spreadsheets. There is a way to export the raw data from these charts, however. Please follow this link to find a possible way to do that.
