Matt Knutzen is reporting on the NYPL’s blog that they have updated the Map Division’s Google Earth index to the digitized New York City map collections. The index now includes “more than 2000 maps from 32 titles, organized chronologically and geographically by borough, all published between 1852 and 1923.”
Here are Knutzen’s recommended ways to search for maps using the index.
1. Select a borough and vintage using the folders from the list on the left sidebar.
2. Double click the map to fly to your chosen location, then use the time slider at the top left of the map frame to narrow the chronological search scope.
3. Enter a street address in the “fly to” search box, then use the time slider.
Once you’ve located a historical map coverage, scroll your mouse over the area and click. A popup window will allow you to access bibliographic information and a digital copy of the historical map.
