An online archive is showcasing the University of Nebraska-Lincoln's historic photograph collections.
The user-generated archive features historic photos, videos, audio recordings and personal collections. Images have been posted regularly to the Historypin website since 2012.
The website allows users to post historic content, using the location and date to "pin" the item to Google Maps. Computer users with Google Street View can overlay the historic photographs on top of the current location to make comparisons.
Posts to the site are also being shared via the university Archives and Special Collections Twitter feed.
