How do people understand what goes on in cities? What types of communications take place in public spaces? These are a few of the questions that the Urban Archives group at the University of Washington is interested in exploring. Comprised of a broad range of scholars, the Urban Archives group hopes "to create a conversation between scholars, artists and activists interested in a variety of issues related to communication in public spaces." On their homepage they have assembled a number of resources for visitors, including links to their digital collections, their wiki, and their weblog. In the "Digital Collections" area, visitors can look at areas that cover yard art, electric signs, graffiti, windows, and "ghost signs", which are fading old advertising images and murals. Visitors can also perform keyword searches across these collections as well. Their weblog is worth a look as well and it seeks to document changes in the urban landscape of Seattle, and it does a good job through its thoughtful posts and accompanying images.
