What is literary quality?

What do international festivals look for when they invite authors and artists to their programme? How do international literary juries select their winners, and what do publishers seek in new authors? Have the ideals for what constitutes literary quality changed in the past five years?

Director Nick Barley of the Edinburgh International Book Festival, director of Aké Arts and Books and publisher of Ouida Books in Nigeria, Lola Shoneyin and director Michael Kelleher of the Windham Campbell Prizes, meet professor of Nordic literature Eirik Vassenden for a discussion.
