From the AHA Blog:
The Center for Research Libraries (CRL) is conducting a series of case studies, funded by the National Science Foundation, to examine the longevity of digital resources. To obtain scholarly input on these studies, CRL is hosting a series of brief (22.5 minute) online forums for researchers in the fields of history, social sciences, and chemistry. These micro-webcasts are free and open to interested researchers and scholars, and cover the following topics: The Historical Record in the Post-Newspaper Age; Political Science, Sociology, and Economics; and Chemistry.
From the series' Agenda:
Digital technology has revolutionized the very nature of scientific and historical evidence. Today’s research data exist in many electronic forms, such as news Web sites, computer models of chemical compounds, and public opinion data sets. These new types of evidence defy the traditional ways libraries and archives have preserved information--putting much historical and scientific evidence at risk.
