It's the 130th anniversary of writer Katherine Mansfield's birth, and her home town is going all out to celebrate the life of one of its favourite daughters. Wellington Arts Festival KM130 encompasses theatre, art, screenings, talks and a birthday party. Nga Taonga Sound and Vision are contributing with online items relating to our greatest short story writer, featuring a Spotify playlist that includes Katherine's favourite singer, Raquel Meller from Spain. But there are also documentaries including interviews with Katherine's elderly sisters. Lynn Freeman talks to Nga Taonga's Sarah Johnston about some of the other treasures in the online exhibition, which goes live this Thursday.
