The festival said: "The Book Festival will provide a neutral forum to facilitate broad, open-minded dialogue between authors and audience members who are keen to look forward, past the immediate politics of the vote, and envisage the shape of things to come."

The veteran jouranlist Kate Adie will deliver the annual Frederick Hood Memorial Lecture, Patrick Ness delivers The Siobhan Dowd Trust Memorial Lecture, and the winners of the James Tait Black Prize and the Edwin Morgan Poetry Award will also be announced.
A series of evening debates will tackle subjects including The Union and the implications of the referendum vote for the rest of the UK as well as "Surveillance and The Self" and ageing.
Nick Barley, director of the Edinburgh International Book Festival said: "The Book Festival provides a crucial forum for dialogue, where we can listen to and learn from one another, particularly in this year of momentous events in Scotland.
"Our thought-provoking conversations with both authors and audiences will permeate through Charlotte Square Gardens as we welcome world-renowned writers and thinkers from many countries and cultures to Edinburgh, some for the first time in their careers.
"We offer a platform for emerging voices that are set to shape the world's literary stage in years to come and launch some of the most talked-about books of the year.
"Whatever the outcome of the vote on 18 September, we provide a space to view the coming changes from the wider context of the historical events that brought us to where we are today - from the Battle of Bannockburn to the end of WWI and the British Empire, the creation of the Commonwealth, the recent economic hardships and even last month's European Elections.
As previously announced, the festival will also feature drama, in tandem with the Scottish theatre company Grid Iron.
Four writers, Kei Miller, Chimamanda Ngozi Adichie, Kamila Shamsie and Christos Tsiolkas, will produce brand new pieces of short fiction.
