The Public Art Archive was launched in 2009 as a free resource for comprehensive data and extensive information about thousands of public art installations across the United States. New users should visit the About area for information about the functionality of the site and its history. After a quick visit here, the Browse tab filters this information by artist, collection, location, materials, work type, placement and year. Those unacquainted with the world of public art would do well to start in several large cities like Chicago, San Francisco, Seattle, and Miami. The clickable map interface makes it easy and quite enjoyable to look at different cities and regions quickly. Browsing around by year is interesting as well; the works are listed chronologically all the way back to the year 1802.
