The ODS was published in 28 volumes between 1919 and 1956 by the Society for Danish Language and Literature (Det Danske Sprog- og Litteraturselskab).

A digitized version of the ODS has been maintained by the Society for Danish Language and Literature since November 2005.

This organization also maintains a sister dictionary Den Danske Ordbog covering Danish language use since 1950.

In addition, the society maintains Holbergordbogen, named for the 18th-century playwright Ludvig Holberg, covering language use between 1700 and 1750 and a digital version of Moths Ordbog a Danish-Latin dictionary from around 1700.
