I want to add one more, but I'm not sure if it's still available as it goes way back. It is 'Gary Player's Golf Class'. This was basically a series of illustrated tips covering the whole game. All very well and easily explained. I turned to that when I first picked up a golf club and it was very useful.

There's so much available now, some of which is very technical. I think the real key is to find a type of instruction which works for you. A large part of that is how you visualise the concepts within your swing. Gary Player is very good at discussing concepts that everybody can employ and, as I say, covers all aspects of the game.
