How do you store and catalog your vinyl?


Just curious how members store, sort and catalog their vinyl collection.
With less than a 1000 I have a hard time remembering just what I already own and have purchased duplicates by mistake whilst at the LRS.

How do you store them?
How do you sort them? Alphabetical or genre or year?
Catalog? In the good old days probably in a note book modern equivalent would be a word document or excel spreadsheet.

Very interested to hear what you do and how you manage that massive collection.

Easiest method is to catalog them using Discogs. The app is very easy to use and you can then access your collection on line plus see the value 
Ah yes good job we are in the modern age, there's an app for that lol.

How do the owners of mega collections store them and organise them physically.
Has to be a daunting task!
For example I read in another thread of someone having 25000 lps and knowing people who had a million of them.
Say what?
Just HOW in the world do you store them AND be able to access them and actually find something you are looking for??
Alphabetical by composer, band, artist. Within a given letter it is totally disorganized though I tend to try to clump like composers, bands, artists for ease of grab. Years ago I bought these white plastic dividers with big black letters so I can see in low light where to begin picking though the chaos.
