The twelfth conference of the European Federation of the National Institutions of Language (EFNIL) at the Accademia della Crusca dealt with the increasing tendency to use English as the language of academic instruction and research in Europe. This development can be seen as progress in international scientific communication at the cost of all languages other than English. The volume presents general reflections, reports and discussions on the linguistic situation at the universities of various European countries, some with a historical perspective. As a conclusion it offers a -Resolution of Florence concerning Language Use in University Teaching and Research- in the 26 official languages of most member states of the European Union and other European countries."
