I have six drawer DVD towers. Each drawer holds 100 discs. The disc sleeves are numbered from 1 to 600. As soon as I buy a new DVD/4K UHD disk I enter it into DVD Profiler and assign to it the next number in line in the DVD tower. In a very compact space I have 600 discs and all of the information on them I can get from my DVD Profiler database. As others have been mentioned, I buy the movie not the case. In addition to the current crop of approximately 300 Blu-rays and 150 4K discs, I also have two other towers with almost 800 DVDs. That’s over 1200 movies that take up very little space. I would hate to think, and my wife would not tolerate, how much space 1200 would take up. Periodically, I will print out on photo paper A three to a page listing and inserted into a big three ring binder that sits on the coffee table. Whenever someone comes over they get a big kick out of sitting with the disk binder and perusing all of the available movies. Since each page lists the collection number, it is simple enough to go over to the tower and pull out the disc that we want to watch. The cases and inserts go to the trash.

No, no no, you're all doing it wrong! 

I store all my DVDs & BDs in these boxes.  I've three that sit under the sofa out of the way, but are easy just to pull out when I need access to them.  Discs here are stored/sorted in the order I buy them (with the storage numbers referenced via Profiler that I've installed on a small Android tablet I keep just for this reason), unless a gap opens up where I've got rid of something for some reason, when I'll fill that first.  Nearly all the cases I've disposed of (mostly given away via Freecycle), but the sleeves, slip covers and any inserts, booklets etc I keep in A5 plastic pockets in A5 leaver arch files on some shelves in my hall.  There are presently 28 of these.

However...

I keep all my music-related (live performances etc) discs (with their original cases etc) (and quite a number of VHS tapes) on there own shelves (in my hall).  These are stored alphabetically (with the media types and different case sizes mixed up together), as it's not too much bother to move them when needed to make room for something new higher up the alphabet.  The exception are old bootleg VHS tapes, which sit on top of the shelve units.

All my TV series and programmes are in the hall too, but in separate shelf units.  These are also stored alphabetically, and within franchises normally chronologically.  Again, like the music the media types and cases types are mixed up.  However, bigger TV box sets get stored sort of on top of the shelf units and a book case in a quite random way, to use the most of the available space as the shelves are basically full now.

However...

In the living room are shelf units with all my Marvel, DC and Doctor Who related discs/cases, both films and TV.  Doctor Who is stored in chronological order, (except box sets containing more than one story, which are then stored where the oldest episode in the box would be placed.)  DC and Marvel have some degree of chronological storage, but I also take into account their release dates and which sub-franchise they're related to as well. In all cases media types are mixed together.

Also in the living room are shelf units for any other releases that have more than one disc to a box/package, or an unusual case or cover, plus all my UHD discs; (if they didn't have any of these things they'd be in the storage cases under the sofa).  These are stored alphabetically with the media types mixed together.  A few large box sets get stored on top of the shelves just because they look nice and use up the 'spare' space there.

All my non digital games are in the living room too (along with all my CDs, cassettes and vinyl).  These are again stored alphabetically, although in the case of my cassettes, vinyl and CDs, these are also sorted by media type and size first, with any unusual sizes kept separately.

In the bedroom are my audio books.  These are stored together by franchise, with some attention to chronology.

See, much simpler and straightforward.

And where do you store your wife?

The kitchen, obviously! Duh...

I'm afraid there isn't a woman on the planet stupid enough to take on that role.    Even if there was, I'm not sure she'd want to live in what's basically a cross between a man cave, a home cinema in a shoe box, a Blockbusters store and a record shop, stuck between posters (nicely framed) of a Spitfire, the Enterprise (NCC1701-D), Alyson Hannigan, Sid Vicious, Ani DiFranco, and Tom & Jerry.

The living room window sill is full of cacti though.

I see your cacti and raise you three succulents:

I keep the discs in boxes in wall unit shelves and one 5' spinner shelf.  Along the wall are sorted alphabetically.  The spinner shelf has 4 sides:  Comic Book/Superhero, Animation, Criterion, & Graphic novels (actual books).  And my 8 year old daughter has her own smaller shelf that defies sorting.

Oh, that is quite lovely. Nicely done paulb.
