This digest of key science and engineering indicators draws primarily from the National Science Board's two-volume "Science and Engineering Indicators, 2008" report. The digest serves two purposes: (1) to draw attention to important trends and data points from across the chapters and volumes of "Science and Engineering Indicators, 2008," and (2) to introduce readers to the data resources available in the main volumes of "Science and Engineering Indicators, 2008" and its associated products. The appendix of this digest provides a detailed catalog of subjects included in "Science and Engineering Indicators, 2008."
