Locked Cage Nerd Match

I've spent a big chunk of the past two weeks cataloging every book in the joint and breaking them down into general categories. Until the miracle happens and I win the lottery, I won't have a house big enough to accommodate the whole kit and caboodle (with what's in storage, 10K to 15k books). I've been thinking of ways to articulate the books so that similar themes are linked and I can get what I call 'straight shots'- reading a string of books on similar themes (like how to get blood out of wall-to-wall carpeting.) Dewey is more about placement on shelves and not particularly helpful, especially for a home lie-berry, so I've started tagging the hell out of the books, trying to link together as many of them as possible in as many ways as possible. My goal is to develop a Unified Theory of Everything, to be used for world domination. I'll need minions; applications are available upon request. Arise! Go forth an conquer! One of you pick up a double macchiato and bring it back to me. Work it out yourselves, you're world-dominater minions, dammit! Fine, you in the back, the new guy. Bring me a double macchiato and make sure this time they give you a sleeve! Just ask for it! NO! Wait. You're a minion; a valued, self-empowered pawn of my will. Demand it.
