The Source Book contains 75 excerpts from the writings of Western mathematics from the thirteenth to the end of the eighteenth century. The selection has been confined to pure mathematics or to those fields of applied mathematics that had a direct bearing on the development of pure mathematics.

The authors range from Al-Khwarizmi (a Latin translation of whose work was much used in Europe), Viète, and Oresme, to Newton, Euler, and Lagrange. The selections are grouped in chapters on arithmetic, algebra, geometry, and analysis. All the excerpts are translated into English. Some of the translations have been newly made by Mr. and Mrs. Struik; if a translation was already available it has been used, but in every such case it has been checked against the original and amended or corrected where it seemed necessary. The editor has taken considerable pains to put each selection in context by means of introductory comments and has explained obscure or doubtful points in footnote wherever necessary.

The Source Book should be particularly valuable to historians of science, but all who are concerned with the origins and growth of mathematics will find it interesting and useful.
