Duden, a series of dictionaries published by the Bibliographisches Institut, Mannheim. It originated with the volume Vollständiges orthographisches Wörterbuch der deutschen Sprache (1880), compiled by Konrad Duden (1829-1911), a schoolmaster; it became (and in its most up-to-date form remains) the standard authority for spelling.
This work is the foundation of Der Große Duden, which comprises ten volumes: (1) Rechtschreibung; (2) Stilwörterbuch; (3) Bildwörterbuch; (4) Grammatik; (5) Fremdwörterbuch; (6) Aussprachewörterbuch; (7) Etymologie; (8) Vergleichendes Synonymwörterbuch; (9) Hauptschwierigkeiten der deutschen Sprache; (10) Bedeutungswörterbuch.
A separate Duden was published in the DDR (Leipzig). The nearest rival of Duden is Knaurs Rechtschreibung—Fremdwörter—Grammatik (1973), which also provides interesting examples of changes in contemporary use of the German language. The extensive volume Duden. Deutsches Universalwörterbuch (2nd rev. and ext. edn., 1989) takes account of the special needs of foreigners. The need for future reviews of the more complex orthographic rules, envisaged by Konrad Duden and recognized at the 2. Orthographische Konferenz in Berlin in 1901 (ratified in 1902), became more pressing in the latter part of the 20th c. In 1986 a conference was convened in Vienna to consider proposals for stringent reform. It was followed by another conference in 1990 which was attended by representatives of Denmark, Italy (South Tyrol), Liechtenstein, Luxemburg, Romania, and Hungary in order to ensure the consensus at which Austria, Germany, and Switzerland aimed, which was provisionally achieved. However, the hotly debated new rules were disputed by various German Länder and it was not until 1 July 1996 that they were ratified. Less radical than had been anticipated and instantly effective, they do not invalidate the old rules until 2005/6, though their teaching becomes obligatory in 1998. The Institut für deutsche Sprache, Mannheim, is responsible for supervising and reviewing all aspects of German Rechtschreibung. Not surprisingly, notable German authors, foremost among them G. Grass, S. Lenz, and M. Walser, objected to the new rules on the grounds of their timing at a period of economic stringency, but mainly because of the aesthetically detrimental effect of the new rules on the German language.
