The »Handbook of Frisian Studies« is the first systematic overall description of Frisian studies from the early runes to Frisian as a European minority language. The central focus is on the West, East and North Frisian dialects in the Netherlands and Germany, standard West Frisian, the history of the Frisian languages and literatures and Old Frisian in the Middle Ages. Introductory articles give a detailed survey of the present-day institutions and main areas of research and language promotion. The »Handbook« with its 79 articles written by 45 authors aims at providing comprehensive information while at the same time fostering contacts to the neighbouring disciplines.
