​Wolff's new project only lasted 8 years, but by the end, he had proudly established a corpus of 86 works by modern writers, most of them German, as well as from other European countries. Among the authors represented in Wolff's project are artists like Franz Werfel, Franz Kafka, Albert Ehrenstein, Carl Sternheim, Max Brod, Oskar Kokoschka, Gottfried Benn, Ludwig Rubiner and Rudolf Kaiser.


The first edition included a composition by Franz Werfel, a very well-known writer at the time: The Seduction (Die Versuchung). Later, Franz Kafka published his first works in the series: The Stoker, The Metamorphosis, and The Verdict (Die Heizer, Die Verwandlung, Das Urteil).


In general, the classic markers of literary expressionism can be seen: criticism of the circumstances of life at that time, the expression of the author's personal impressions of life in a literary manner (thus, the term Expressionism), as well as use of modern language.  Many of the books were published in additional editions by Kurt Wolff, who in 1919 moved from Leipzig to Munich. In 1921, the last volume of the series, the story The Death of Moses by Rudolf Kaiser, was published. Despite the Nazi's attempts to erase all traces of Expressionism, many books in the style, in general, and in Wolff's series, specifically, survived in private and public libraries.  In the 70's and 80's of the 20th century facsimile editions of all the volumes were published, which is indicative of their continuing relevance.


Some of the booklets in the series "The Last Day" can be found in the National Library. In addition, some of the personal archives of a few of the authors, who donated their works to the series- Albert and Karl Ahrenstein, Oskar Baum and Rudolf Kaiser- can be found in the Archives Department of the library.
