That site and programme is spectacularly useful

Thanks very much

The Complete Book by Mark Hanson is very good as is the Acoustic Guitar playing book by the guy who used to play acoustic for simon and Garfunkle (forgot his name sorry) Good slide player and there was an argument about who played what between him and Ry Cooder on that pretend Robert Johnson movie where there was a guiatr shoot out at the end with Joe Satriani

I will be amazed if any of that is helpful
