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 have about 7,000 LPs. About 3,000 are classical, about 3,000 are jazz; and the rest is mostly rock with some folk, "world music" etc. The classical is arranged in chronological order by composer, i.e., Bach before Haydn before Mozart before Bethoven, and so forth.. The jazz is arranged in alphabetical order by composer, as is the other stuff.
My collection is much smaller so alphabetical by last name of composer or artist works for me. If a group, I organize alphabetically by first letter of first word in name (ignoring, "The"). Had I a collection as large as yours, would sort first by genre and then alphabetically (as above) within the genre. Have fun.
The classical is arranged in chronological order by composer, i.e., Bach before Haydn before Mozart before Bethoven, and so forth.

The chronological system really appeals to me for the classical. I have about 500 classical LPs. The last 80-85 years is a different story.
For the most part, I'm in line with the above posters. However, with a slight twist. I'm into 12" singles. So, in addition, to a separation by genre, I have a separation of 12" singles. Also, I have a separation for what could be considered "audiophile" recordings or brand new releases (not reissues).
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.
