How do you keep track of your cards, stock that is?

I'm still thinking about how to sort my vampires. I store my library cards into drawers, sorted :
- by discipline
- multiple disciplines are apart (including 3-ways but not the bloodline disciplines cards with outferior)
- master
- event
- master skill cards
- master hunting grounds (could be mixed with masters though)
- disciplineless action (whatever their requirement)
- disciplineless reaction (whatever their requirement)
- disciplineless combat (whatever their requirement)
- disciplineless combo (whatever their requirement)
- disciplineless allies
- disciplineless retainers
- disciplineless equipment
- disciplineless political actions
- imbued related cards
Of course, inside a category everything is sorted alphabetically. For big collections (disciplineless actions, master cards...) I have some separators for each letter.

When building the deck, I use ARDB. When done, I pick up the cards.

My cards are in big 1600-3200 card cardboard boxes. Vampires are separated by clan and sorted by name. Other cards are separated by cardtype and sorted by name. I have my whole inventory stored in Secret Library, which I also use when constructing decks.
