I'm looking for a short story about a man who forgets to return his library book. A computerised system takes over and everything goes from bad to worse. The book he did not return is 'Kidnapped' by Robert Louis Stevenson, so the man ends up on a kidnapping charge, which changes to a murder charge when the computer learns that RLS is dead. It must be from the 60s or 70s.
