For more than a hundred years, The Society for Danish Language and Literature has been editing literary works and documenting the language from the earliest period to the present day. More than 200 titles and 800 volumes have been published within the fields of bibliography, medieval diplomatics, fiction, poetry and drama, lexicography, language history, grammar and corpus. In this talk, a selection of projects and resources will be presented, with special emphasis on the lexical resources. In particular, the perspectives and challenges of linking digital data will be explored.
