The University of California have created Calisphere as a gateway to more than 150,000 digitized items. These digitized primary sources include photographs, documents, newspaper pages, political cartoons, works of art, diaries, transcribed oral histories, advertising, and other unique cultural artifacts that reveal the diverse history and culture of California.
As part of the Calisphere project a number of Google Maps have been created to showcase some of the digitized historical photographs in the collection. Five maps have been produced to display the photographs by category. The categories are; transportation, city scenes, civic buildings, disasters and everyday life.
Each of the maps displays the location of the photograph with a small thumbnail image. If you click on the thumbnail you can view the image in an information window and click through to get more information about the image.
