In 1961, 50 years ago, Paul Nizon began keeping his journals. Daily, he notes what is important to him, thus keeping his perception of himself and the world alive. What started as a record of daily life, autobiography, and workshop report has long since grown into something independent, representing another side of Paul Nizon's work. Four journals have been published so far, and from book to book, it has become increasingly clear that someone is writing their life, inventing their life story. In "Urkundenfälschung," the journal covering the years 2000 to 2010, there are breathtakingly beautiful observations and stories from everyday life, insightful portraits of writers and contemporaries, disturbing dream sequences, and exhilarating city miniatures that tempt one to embark on an immediate journey. We follow how the novel "Das Fell der Forelle" takes shape and read about its development.
