This yearbook has been published since 1993 and is regarded as the most important institution in research into Hofmannsthal. On the one hand, it places the works of Hugo von Hofmannsthal (1874–1929) in the aesthetic and socio-historical context of modern European culture. According to the Neue Zürcher Zeitung , its publication of previously unpublished correspondence is one of its particular merits. On the other hand, contributions from renowned experts in literature, the fine arts, philosophy, psychology, politics, and in dance and theatre at the turn of the century are also collected in this yearbook.
