Is that as true of a book as a Tweet? Why should that be? It also looks at why writers, journalists and artists choose to do work under an assumed name, now and in the past. Writers include: Julian Baggini Hilary Mantel Valerie Plame Wilson Kaya Genc filmmaker Alejandro Jodorowsky Turkish journalist Can Dundar.
