Hey, I know there's FM and Pepin on here from Brasil and Gizlivadi is in Chile.... No, I'm not asking you guys to do my homework for me.

I'm just looking for any heads-ups on research ideas from those more knowledgeable on South American history than myself.
Anyway, I had a question for you guys (and anyone else who would know):
For my history class, I have to write a paper on the South American Independence movements, and I'm starting to look around for a few primary sources (ie, letters, correspondence, et cetera from, say, Simon Bolivar or some other important figure) and I was wondering if anyone had any ideas for good things to look for. My topic deals with the initial motivations for the independence movements and the expectations of the leaders for what sort of nations would result-- monarchies, republics, confederations, et cetera.
I already have Bolivar's Jamaica Letter, and I need at least two more. I'm planning on checking out a lot of stuff that I already have leads on over the week, but I need to find at least two more primary sources. Anyway, I was just wondering if any of you would know of some important historical figure or writings I should specifically look for.
