The design of this book’s interface played an important editorial role in its construction, organization and navigation. Based upon the use of idioms in Karl Kraus’s Die Fackel, an early 20th-century Viennese journal of media criticism, the dictionary is intended for use by Kraus scholars, literary theorists and linguists interested in lexicography. The dictionary’s unique diagrammatic display helps to identify and organize nine different textual functions for each individual dictionary entry. The primary source material was comprised of excerpts from Die Fackel, which used typography and layout as a rhetorical device. Therefore, images of entire pages became the backbone for the dictionary’s organizational flow and helped inform the dictionary’s typographic choices. Support texts used unusual and complex writing strategies, so the editors and designer worked in tandem to create a unique punctuation system with multilevel quotation marks and variegated reference strategies.
