I have recently just finished a degree, and the best thing I learnt about was a program called 'zotero'. It is a citation program. I wish I heard about it in first year.
PM me if you want more details, but basically there are three parts to it: the program, the web browser plugin, and the MS Word plugin.
With the web browser plugin, you simply navigate to the page of your book on your online library catalogue, and click a button that sucks in all the relevant info.
Then, in Word, you click 'insert citation' and you simply say what pages, and it then does it. It also does a bibliography.
The program ties it all together.
For it to work, there will need to be two extra bits. Firstly, for the web browser plugin to work, there will need to be a special file that tells zotero how to read your Uni's online catalogue. Second, there will need to be another special file that tells it how to format the citation into the required format.
The good news for you is that, given you go to a major uni, and are formatting it into a popular format, I'm nearly certain that both will be included with the program by default.
So, just download the Zotero 'stand alone' program, and then have a play.
It's also completely free
