Volume 3 is devoted exclusively to B. Piłsudski's Ainu-related materials, for their most part previously unpublished. In addition, it comprises Piłsudski's research reports on his expeditions, a superb collection of fifty prayers in Ainu as well as texts and melodies recovered from Piłsudski's famous wax-cylinder recordings of Ainu-folklore of 1902-1903. The bibliographies printed in volume 1 are extensively enhanced. Abundant illustrative material is included.
