A reference to over 500 scientists whose career started around or after the beginning of modern science, taken here to be about the founding of the Royal Society. For each, lists full-length biographies, including autobiographies, in chronological order to demonstrate the historical development. Many of the entries are annotated, again to highlight the historical setting and the author's purpose and sources. Changes in later editions are also noted. In lieu of an index, appendices list scientists by specialty, major publishers, and biographical series. Of potential interest to historians of the book as well as of science.
