Ok right Thanks for all the info folks, I would just like to point out that my local library sort only has books in portuguese, so although your suggestions are well meant it's a bit difficult for me to get my hands on books about trad. british music (NOI)...though the net is a great resource unfortunately it doesn't have everything, that is why I am relying on the good graces of my fellow 'Catters to mail me stuff...so for those interested my snail mail address is:

Alistair Robb Av. Presidente Kennedy, 8014, Candeias, Jaboatao dos Guararapes. PE Brasil.

Thanks :o)
