Getting my references under control?

I'm still in between courses on my History MA (Part 2 does not start until May) but i have made my first step in preparing for the course (which involves writing a dissertation) by buying and installing some software to manage my research.

I have bought EndNote, which works with Apple Pages (which is the word processor i use) unlike some other softwares. Its also a heavy weight application and i got a nice academic discount. Now i shall familiarise myself with the software as much as possible before beginning my research in earnest sometime in March (perhaps).
