Manga is digital for me.
For the anime, I have a four-shelf thing for my anime discs
Top row, discs I haven’t watched yet (this is huge because of a 30 anime for $30 deal, and most are midseason stuff from when like 2-3 episodes were on a disc). No real order other than stuff I want to watch next are first, then any multiple parts that I have at least vol 1 of, then other series I don’t have vol 1 of.
The other three are in alphabetical, but with another rule first.
The second shelf is for anime with sub and dub, but I only watched it one way. Basically these are series I bought blind, enjoyed, but haven’t taken the time to watch the other language.
The last two (because I have that many), I have watched, and if it has sub and dub, I have watched both (some have jumped to this level because I have watched the sub online, and I was just waiting on the disc to watch the dub)
