FRESH: Frontier Research in Economic and Social History, is an international group based in the Department of Economics at the University of Copenhagen. As the organizers explain, "the meetings build on the concept that scholars present their ongoing research at an early stage, i.e. before it becomes published as a working paper or the like, and certainly before it is published in journals or books. The main aim of the meetings is to gather researchers in a friendly and non-imposing environment where they can present their research and receive constructive criticism from their peers." Researchers in any field of economic or social history are welcome to register as members; there is no charge. Upcoming meetings will be held in Gothenberg, Antwerp, Montevideo, and Münster. The program for the most recent meeting in Moscow is available on the FRESH website, as are programs from other previous meetings.
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 .
