Ordbog over det danske Sprog

Ordbog over det danske Sprog (Danish: "dictionary of the Danish language") or ODS is a comprehensive dictionary of the Danish language, describing its usage from c. 1700 to 1955 in great detail. So far 28 volumes have published from 1919 to 1956 with five supplementary volumes published 1992 to 2005. The project was begun by Danish linguist Verner Dahlerup. The full version of the ODS has been available in an online version since November 2005 as part of the project ordnet.dk.
