Digital Critical Edition of Nietzsche’s Works and Letters (eKGWB)


The Digitale Kritische Gesamtausgabe Werke und Briefe (eKGWB) is the digital version of the German reference edition of Nietzsche’s works, posthumous fragments, and correspondence edited by Giorgio Colli and Mazzino Montinari (Friedrich Nietzsche, Werke. Kritische Gesamtausgabe, Berlin/New York, de Gruyter, 1967– and Nietzsche Briefwechsel. Kritische Gesamtausgabe, Berlin/New York, de Gruyter, 1975–). The eKGWB is edited by Paolo D’Iorio and published by Nietzsche Source.

The digitized text of the eKGWB was proofread against the printed edition. It is the first edition to incorporate the roughly 6,600 philological corrections previously published in various printed commentaries. These corrections are highlighted in the eKGWB, with linked citations that provide the uncorrected text of the print version. 

The eKGWB interface allows readers to consult, cite, and copy the text; to search the entire corpus or delimited parts of it; and to generate lists of search results with or without the surrounding text. All texts and search results can be printed.

The eKGWB is encoded in XML-TEI to ensure interoperability with other text archives. The edition uses a classification system that provides each work, chapter, aphorism or fragment a unique and stable internet address. To facilitate cross-referencing between paper and digital editions, the sigla used in the URL for the eKGWB correspond to the standard abbreviations established by the Colli/Montinari print edition. For example, the first section of The Antichrist can be reached at the following address: By using stable URLs with conventional sigla for both published works and unpublished material, the eKGWB is a reliable and citable source for academic research.
