From the reviews:
This is one volume of an ambitious project to publish David Hilberts lectures on the foundations of mathematics and physics, 18911933. The upshot is a wonderful resource making possible new scholarship on Hilbert as a highly interesting philosopher of physics and epistemologist. Philosophers of physics and those with interests in early twentieth-century HOPOS will find in this book an irresistible invitation to explore Hilbert as philosopher of physics and epistemologist.

This is the second volume published in the meritorious selection from Hilberts unpublished lecture notes of courses on the foundations of mathematics and physics . The volume is completed by several tools that make access to the material easier: a complete list of Hilberts lecture and an index of names and subjects. an excellent volume that perfectly fulfils the editors desire to bring out the significance and potential of Hilberts contributions to the foundations of physics in all their aspects .

This splendidly edited and rich volume sets a remarkable store of Hilberts ideas before the public . The book and each of its six chapters have excellent introductions by the editors have taken the sensible decision to leave Hilberts text in its original German. they have judged that the best (a translation) would have been the enemy of the good (a well edited book that actually exists) and for choosing the good, and much else, we should thank them.

David Hilbert (1862-1943) was an outstanding mathematician whose Gesammelte Abhandlungen (Collected Works) were published during his lifetime, between 1932 and 1935 in three volumes. this volume inhabits a place somewhere between a definitive critical history and a student edition, although readers of this beautifully printed and well bound book will no doubt appreciate having some important and interesting papers by Hilbert between its covers.
