The National Genealogical Society (NGS), of which I am a member, sends out an article each week called “UpFront with NGS. It contains a paragraph or two of some genealogy news that may help you to dig deeper into your family research. Pasted below is just one of this week’s articles that I thought may have some usefulness for others.
“The United States Geological Survey (USGS) launched a Historical Topographic Map Explorer, allowing one to easily pore through the agency’s expansive collection of more than 178,000 of the USGS’s maps dating back to 1884. When you enter a city, you then click on the map and a timeline of available historical maps is revealed. Select a map and you can then see if overlaid on the original map (you can adjust the transparency) and even download the map. Very cool!”
