Not sure if this question has been asked before (demos or someone else can point me to a previous thread if it has), but I was wondering the other day how many copies of Mike's books have sold worldwide over the last forty years or so. Taking into account the numerous UK reprints in the 70s and after, the various reissues of books in the States, all the foreign language editions etc it must be a lot.
I'm not seeking any confidential information, or even an accurate figure, just a rough estimate of some kind. Anyone know? Mike?
