The diversity of the European languages is an essential component of the cultural wealth and identity of our continent. In several overview papers on the present linguistic situation within the European Union and in a series of reports on the language policies of various member states, congruencies and discrepancies between linguistic concepts and programs of the institutions of the Union itself and those of individual constituent countries are being described and discussed. A resolution on national and European language policy, approved by the General Assembly of EFNIL, the European Federation of National Institutions for Language, and presented here in all official languages of the Union, concludes the discussion with a call for the improved co-ordination of national and European language planning based on reliable empirical facts.
