How do you organize your LPs?


So I've accumulated upwards of 3,000 records and storage is getting out of hand. I currently have a built-in that holds about 150 of my most listened to. I have 12 Sleeve City boxes that hold 60 each. The rest (a majority) are in other boxes, cabinets, book shelves, etc.
I am planning some cabinetry that will hold ALL my records with room for additional. My question is how do you arrange them? Alphabetical? Genre or some hybrid. I can't continue to look through 500 records to find the one I am looking for.

Mine are a jumbled lot. When I want to play something, I'll have to look for it everywhere. In the process, I'll find some lp's that I would have normally skipped right past had they been in any sort of order. Maybe even forgot I had them. This way they're never overlooked as they're looked over. Staying acquainted with them ALL. I'll pull them out a tad to mark them for playing in the near future.
I hate seeing records stored like books! I have mine set up like a record store, by artist but in no particular order. That way I have to flip through them looking for stuff. Although I know where most are, I keep finding forgotten albums which is a nice surprise.
Oh the unanswerable existential questions, the questions that have no answer. I presume we have all seen the film High fidelity. One of the questions that proves women are from Venus, men are from mars, or is it the other way round?. Women will never understand the importance of this subject, with the honourable exception of our lady Audiogon members.

I put all modern music together alphabetically, including rock, blues Jazz. Classical is the problem, because of the higher numbers of mixed discs, but again alphabetically by composer, with the largest piece of music as the composer. Definitely not perfect, but it serves
