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.

I generally arrange my LPs in "record store" alphabetical order and separating out a few specialty genres as well as titles for easy access. I also separate out specialty pressings such as direct-to-disk, half-speed mastered, and the like by record label.

Moreover, I found the best thing that you can do to make your life easier is to locate the majority of your LPs on shelves located at or slightly above or below eye level. It's a lot easier to stand while flipping through LPs rather than bending over or crawling on your knees.
Three main groups. Classical, Jazz, Rock.
Alpha by name of Artist/composer.
Foor Classical after by Composer, arranged by size of group, Sonata, Duo, Trio etc. Withing each, Say Beethoven Fifth Symphony then by conductor.
For Jazz and Rock, after each primary artist or band name, in chronological order. (Which really helps but is hard to keep straight for many groups, but worth trying to do. It would be great for Classical too, but is way too complicated to keep straight, so i go with the other method in Classical.)

Actually a totally chronological order only, would be amazing. And informative. But total Hell to keep stright. And to find stuff unless you had a good handle on the dates etc.
Don't, just file them away as purchased, with an collection number I assign. I do have a data base, organized initially by collection number but can be sorted any which way.
I may have several groups of vinyl:

1. Disposal group is usually for worn records that are going to donation facility within close time of next year:-)
2. For sale(The largest group) that is usually sorted by genres(group of jazz, rock, classical and others)
3. In-out collection group consists of records that I'm listening to and sell at the same time sorted by band name. Band member's solo albums may be fit onto the band name as well such as John Paul Johnes or Rober Plant records can be found in Led Zeppelin pile.
4. In collection is sorted similar to In-out collection with the difference that it's not currently for sale.

Overall have near 10,000 records +-
