This issue of Diogenes includes short papers by prominent officers of 18 of the member-associations of the International Federation for Modern Languages and Literatures (Fédération Internationale des Langues et Littératures Modernes - FILLM) with a view to introducing and explaining the history, purpose, and function of these international learned societies representing different branches of the modern languages field at a time when the role of such bodies is often questioned even by professional academics working within the discipline, and their very existence largely unknown outside it, even to educated persons. The FILLM is one of the earliest member organizations of the International Council for Philosophy and Humanistic Studies (CIPSH) which had indeed had a prior existence since its foundation in Oslo in 1928 as the Commission Internationale d'Histoire Littéraire Moderne and was subsequently reorganized in its present structure in 1951 following the formation of UNESCO.
