How do you sort your LPs?

I sort by Genre, then by pressing ie. UK, MOFI, Japanese etc, then alphabetical order by Artist. 

By coincidence I just sorted 750 albums by artist and title. I keep track of them on Discogs...I exported a csv file... opened in Excel....got rid of most of the columns...copied and pasted into Wordpad (Word and Notepad proved to not work well)....now cross checking and making sure they have been sorted correctly and adding ones that I hadn't entered into Discogs.

Thanks to all for your suggestions and opinions.

I have a decent size (to me) collection of LPs. Most of them are originals, meaning I bought them new when they were first released, and are in great condition. I still buy LPs so the collection is still growing but at a reduced rate. I'm trying to enjoy what's here hence the quest for better organization.

Now, they are loosely grouped by genre but not all in the same place. For example, there is the classical section on the right side of the room (the I don't listen to often side) and the classical section on the left side of the room (the most listened to section). I chose genre because that's how I usually select what to listen to. For example, if in the mood for jazz then I go to the jazz section and then narrow it down from there. I'm not good at remembering names but I remember cover art.

I'm not obsessing, at least I don't I am. My goal is to spend less time searching and more time listening. Also, I want to weed out between 1000 to 1500 LPs that will never be used (by me) again. The "I listen to these LPs most often pile" seems to get out of control too often. 

Thanks for the suggestions of Discogs and similar. I will check it out.

Major majority in my small(300) album collection is jazz. So what has worked well for me is instrument of artist. Piano, guitar, sax, trumpet, drums, vocals.
