America on the Move is a physical exhibit at the National Museum of American History with a strong online component. The Museum’s online transportation collection includes more than a thousand artifacts and photographs. The web version of the exhibit provides numerous ways to explore the material, including a chronologically divided set of sections spamming times pre-1876 through 2000. In addition to the visual materials, there are a number of thematic "stories," featuring many essays divided into topics such as "work and lesiure," "technology," and "immigration." The site also includes a list of learning resources such as self-guided tours, a "classroom activity guide," a reading list, and a list of other web links.
The Princeton University Library has digitized a number of posters from the Interborough Rapid Transit Subway Company . The posters, designed by the public relations firm Ivy Lee, were displayed in subway cars to provide information to riders about changes in fares and routes, safety issues, and other matters of interest. The collection consists of 385 images dating from 1918 to 1932; many of them provide financial information about rates, company dividends, and a general look at an early rapid transit system. October 29, update: Jonathan Rees over at "More or Less Bunk" was moved by this post to go off in search of a better site, and found the massive collection of the London Transport Museum , which displays over 5,000 items in a searchable collection .
