Lists the practical problems found in the manuscript of Book III of the Algebra which were not included in the printed text. The author believes that their omission reflects the influence of Bombelli's discovery of Diophantus.

This is a first attempt at consolidating and extending the lists of biographies of historians of science compiled by George Sarton, Aldo Mieli and François Russo. In doing so, a systematic examination has been made of the Dictionary of scientific biography, and of the relevant parts of the Isis cumulative bibliography and Kenneth May's Bibliography and research manual of the history of mathematics. Material for a supplement is being collected. Readers are invited to send additional material along with their comments.
