Alan Taylor, "Fifth Avenue Then and Now, a Century of Streetviews in NYC." Atlantic Photo. January 6, 2015.
"The New York Public Library has recently released even more digitized images from their vast collection, including more than 180,000 in the public domain. While browsing, one of the first collections I came across was a book published in 1911, titled Fifth Avenue, New York, From Start to Finish, with wide-angle streetview photographs made by photographer Burton Welles more than a century ago. I thought it would be fun to revisit those same locations using Google Maps Streetview images from today, to see what differences are visible. Some views look remarkably unchanged, while others are completely unrecognizable. The images are stacked on top of each other—unfortunately they never quite lined up enough to make use of my then-and-now fader widget. (Adding a note: I just discovered that the NYPL made their own wonderful then-and-now viewer for this same set of images.)"
