Thanks for the advice Bolanos. I think i'll loan all these books from the library where possible and then purchase the ones I favour. I think it's also a case of continuing research online as well. But thanks so much guys, will definitely look further.
Oh and jujimufu, i'm sorry for posting a thread that is similar to others and, ok, I can't blame you for thinking this thread isn't unique so I apologise - I'll make sure I do a through search next time. I just think your response was unnecessarily patronising and a little rude. But hey i've been on enough forums to know that new guys who come across as being ignorant to forum rules are annoying, so, sorry.
EDIT: Also: although, as I said, I would look into the books mentioned are there well thought of recent books that aren't outdated as well?
