Here’s a fun new site that might help flesh out your research. Historypin, which launched in London in June 2010, is an online tool that allows people to view and share history through Google Maps and Google Street View technology. The site is produced by We Are What We Do, in partnership with Google. The goal is to become the largest user-generated archive of the world’s historical images and stories.
Users can upload and pin vintage photographs onto the Historypin map and layer them onto modern Street View scenes, creating a timeline of views for the location. Stories for that location can be added as well.
The photos currently date from 1840 to the present. At present, you can upload six photos using your Google account and a Picasa album. One of the project’s goals is “bringing different generations and communities together to collect and share the history of their streets.”
