The National Science Board of the National Science Foundation has published the thirteenth issue of this biennial report. Science and Engineering Indicators chronicles overall trends in the development of "science and engineering research and education." The report details tendencies in all levels of education; the science and engineering work force; US, international, and academic research; and public attitudes toward and understanding of science and technology. This issue contains a new chapter, "Economic and Social Significance of Information Technologies," along with several other new and enhanced features (see the introduction). Hundreds of tables (text and Microsoft Excel) and charts supplement the report, which should prove to be an indispensable resource for researchers, reference librarians, and anyone interested in the overall state of science and engineering.
