The special report in this issue includes an analysis of the value of anonymity with articles looking at when it is used and why. Does it pose threats if people choose to write under a pen name? 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 Genç
• filmmaker Alejandro Jodorowsky
• Turkish journalist Can Dündar.

Plus why anonymity is under threat in India, why the people who help out foreign correspondents are under threat once they leave, and Chinese artists who feel under threat outside China.
