Volume 3 is devoted exclusively to B. Pilsudski's Ainu-related materials, for their most part previously unpublished. In addition, it comprises Pilsudski's research reports on his expeditions, a superb collection of fifty prayers in Ainu as well as texts and melodies recovered from Pilsudski'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.
