The correspondence of the linguist Anton Schiefner covers the years 1843 to 1879 and deals with a great variety of subjects. The present volume offers an historical survey on the situation and development of Linguistics of that period, owing to the manifold activities and interests of the author (i.a. Classical Philology, Finno-Ugric languages, Slavic languages, Tibetan, Caucasian languages) and of his correspondents, scattered all over Europe, as well. The present volume is complemented by various illustrations and extensive indices.
