Writer JG Ballard has died at the age of 78. Best known for his books Empire Of The Sun and Crash, both of which were turned into high-profile feature films, Ballard described the majority of his work as "picturing the psychology of the future".
BBC News has a series of tributes from readers, and there are obituaries in The Guardian, The Independent, The Telegraph and The Times.
The Guardian also has tributes by fellow writers, including Michael Moorcock.
