The Secretariat of the European Charter for Regional or Minority Languages has published a booklet on “Protection and promotion of regional or minority languages: promising practices across Europe 2015-2020”. The collected examples of practices can serve as models for knowledge transfer among stakeholders. Regional or minority languages appear here as a living phenomenon used under all circumstances and on all formats, notably in line with the current digital era and the use of IT tools in education, culture, media and administration.
