Supplements would be issued when new features were added for later models , like Air Con, or for a different market or further service instructions incorporated. Later the whole manual would be revised and reprinted as a whole. It especially happens in the early life of a model . I have early SD1 manuals and there are two supplements to the main manual.
Another thought has come to mind, one must remember , the 1970's were the early days of computers and frequent & last minute changes to printed books was not easy and very expensive as the printing plates were fixed . I am a member of the Rover sports register and we reprint the Pre-war Rover manuals, and can now get them economically run off in batches of only 30 or so, whereas only 10 or 15 years ago it was in the hundreds
Ban is strictly correct, we shouldn't have copyrighted material without permission, I mean quite honestly the avatar I grabbed from somewhere is probably copyright that I don't own and I could be hauled before the courts any minute to see the wrath of the Judge
there were all sorts of Copyright issues being fought out on Youtube for years and quite recently with people uploading pop videos/ movies and YouTubes reacts by blocking that video from certain countries
but do we need to worry about Rover manuals/ documentation being shared across this site? I don't think so because actually WHO is going to come after us?
roverp480 thanks for your clarification
