This volume contains six sets of notes for lectures on the foundations og geometry held by Hilbert in the period 1891-1902. It also reprints the first edition of Hilbert's celebrated Grundlagen der Geometrie of 1899, together with the important additions which appeared first in the French translation of 1900. The lectures contain many reflections and investigations which never found their way into print. «
