It was a long, trusting collaboration that is documented here, a dialogue that seeks its equal in scope and intensity within the literary scene of post-war Germany. Literary gossip, confidential communications, and previously unknown details about the creation process of Benn's works are printed here. This volume is also a uniquely comprehensive testimony to Benn's attempt to stage his comeback. Letter by letter, the reader is shown the difference between the author who styles himself as a loner, unyielding in matters of art, and the cooperative publishing colleague. A large, carefully annotated edition that many Benn readers have been waiting for. This volume is being released in an innovative hybrid version: the most important letters by Benn are printed in the book, with brief comments provided in the appendix.
