The list is 57 strong (up from 38 last year) with most entries coming from the US and UK, and there are some pretty big names on there, including Chimananda Ngozi Adichie and Kazuo Ishiguro.
As The Short Review says :
... this is a wonderful move on the part of the organisers, giving much-needed publicity to many, many books not published by mainstream publishers but by small presses without teams of publicists ... . What is also wonderful is that "big" names are alongside newer writers, showcasing that the short story is not just the province of those who have yet to "graduate" to novels!(Thanks Steven of Horizon Books for sending me the news and the links!)
