When Bond arrives undercover in the Caribbean in Die Another Day, one of the things he has with him is a book about birds, entitled Birds Of The West Indies. The book is real, and the author is one James Bond, a name Ian Fleming used for his hero because he thought it was dull and anonymous enough to work for his fictional secret agent. As a side note, another piece of reading material of Bond's in Die Another Day makes a reference to a previous Bond movie: a magazine he's reading while on the flight to the Caribbean features an article about Gustav Graves, where the line "Diamonds are forever..." is clearly visible.
