The period here covered reflects all the great experiences of Rilke's early adult life: his difficult beginnings, his relationships with Lou Andreas-Salome and with his wife Clara, his two journeys to Russia, his contact with the Worpswede artists, the influence of Paris, the revelation of Cezanne. Many of the letters are psychologically revealing; many touch upon characteristic themes, or freshly transcribe experience that sooner or later passes into the poetry.

There are important letters here to Muzot, Lou Andreas-Salome, to Princess Marie of Thurn and Taxis Hohenlohe, and many others. The most significant of the Wartime Letters: 1914-1921 are also included. An Introduction briefly traces the development of Rilke's work during these years; the Notes provide the necessary framework of biographical details and point up significant references to the poetry.
