First published in 1996. The intention of this volume is two-fold: first, to give a chronologically arranged overview of selected data on the history of science in the United States, and second, to orient the reader to the substantial reference literature and research sources as guidance to further study of the topic. The subject areas that are covered include astronomy, biology, chemistry, geology, mathematics, physics, and their related disciplines; areas such as anthropology and psychology are covered to a lesser extent. Science is the central focus, but the content of the work recognizes that the boundaries between subjects or activities are not absolute and certainly not when coverage spans several centuries.
