Improving the Accessibility of the NBER's Historical Data
介绍了将NBER早期手工整理的二战前经济数据集转换为现代可读格式并验证其准确性的工作，使研究者能通过互联网轻松获取这些数据。
Abstract During its early years, the National Bureau of Economic Research (NBER) assembled an extensive dataset on the pre-World War II economy. In 1978, the Inter-University Consortium for Political and Social Research transferred the data from the NBER's handwritten sheets to a machine-readable format. Modern econometric software cannot easily read this format, however, and the data-keying process produced several errors. We have converted the machine-readable dataset to a portable format and verified its accuracy using the NBER's handwritten sheets. The dataset is now available on the Internet and can be accessed using standard gopher or web-browser software.
