Abstract

This has been a great century for logic and the foundations of mathematics. Ewald's excellent sourcebook is a welcome addition to the literature on the exciting developments of this and the past two centuries. The richness of the material on which Ewald is drawing is shown by the fact that he has assembled a broad and representative selection without once duplicating anything to be found in the famous sourcebooks of van Heijenoort and Benacerraf/Putnam.
