Over the course of the James Bond film series, a handful of novelizations have been written based on some of them.
Christopher Wood was the first author to write a James Bond novelization. In 1977, he wrote James Bond, The Spy Who Loved Me based on the film The Spy Who Loved Me which starred Roger Moore as Bond. The book title was changed to avoid confusion with Ian Fleming's novel The Spy Who Loved Me. Later, in 1979, Wood adapted the film Moonraker as James Bond and Moonraker. Wood is the only non-continuation author to write a novelization of a Bond film.
No film was adapted into a book again until 1989's Licence to Kill. John Gardner, the continuation author of the time, was hired to write a novelization of the film. He then followed this up with his adaption of GoldenEye in 1995.
When Raymond Benson took over as continuation author, the task of adapting the films into books fell to him. He wrote novelizations of the subsequent films; Tomorrow Never Dies in 1997, The World Is Not Enough in 1999 and Die Another Day in 2002. To date, he had written the most novelizations, three, and his adaption of Die Another Day is the most recently released novelization.
