The Business History Initiative at the Harvard Business School has launched a website "[t]o facilitate understanding the history of global capitalism in its broad societal context." "Historical Data Visualization" displays "historical data on broad economic, social and political trends both globally and within the United States." Materials include maps (both interactive and static), graphs, and datasets (many of which have raw data in Excel format), divided into categories such as "Commodities," "Corporations," "Managing Distance," and "Politics & Economics."
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 .
