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.
