This collection includes documentation material on the Saru dialect of Ainu, a language which is nearly extinct at present. The collection includes a corpus of previously recorded and unpublished material of Mrs. Kimi Kimura (1900-1988) recorded by Hiroshi Nakagawa in 1977 to 1983 and a corpus of newly collected audio materials with time-aligned transcriptions, multi-tier annotations, as well as translations of transcripts into English and Japanese, collected by Anna Bugaeva between 2007-2009. The materials have also been deposited with Chiba University which serves as a mirror site.
