Leipzig, B. G. Teubner, 1906. 8vo. In the original printed wrappers, without backstrip. In "Mathematische Annalen, 62. Band., 3. Heft., 1906.". A fine and clean copy. Pp. 351-370. [Entire issue: Pp. 329-448.].

First printing of Hibert's important paper in which he addressed a number of topics in the Calculus of Variations and thereby extended the ideas given in his account of the 23rd problem.
In contrast with Hilbert's other 22 problems, his 23rd is not so much a specific "problem" as an encouragement towards further development of the calculus of variations.
His work in the present paper led to a modern definition of the field.
