I'm doing a 4-5 minute oral presentation on Monday about the North / South Divide in the U.K especially aimed at different Languages and Dialects. As Wikipedia as the only source im trying to expand my view of things and i'd like to start off by asking here for advice. I'm basicly going to talk about what different kinds of Language there are, along with dialects and how this affects people.

Is encyclopedia's at the library a good place to start or where would you suggest I looked? I know there's alot of U.K ppl on this site and perhaps in between the 148958496 lines of whine something useful can pop up. Cheers!
