Cataloging Audi Info

[TM]

Question for all of you:
How do you catalog all of the info that you've collected over time?

I have a ton of collected posts and emails that I need to organize in
some fashion and was wondering how you did it. I'm using Outlook and
am thinking of just creating a whole new personal folder just for Audi
stuff and trying to organize everything by subject matter, periodically
archiving the whole mess to CDR.
