Jack, I've told you: do a search on the British library using the term "john pearson james bond biography". Looks for the ealiest published book. It's 1973. It's Sidgwick and Jackson. It's James Bond: the authorized biography of 007. Your own searches have included the term authorised. I suggest you leave the word out altogether and re-do the searches. There can be no accusation of skewing the results if you follow that suggestion. You want an RfC so much, start one. -  (^ • @)
