I use Library Thing. It is free and works great for books, movies, TV series. Anytime I’m browsing the local stores I easily check if if I already own something. Has helped a ton.
This looks neat!
@jqubed @notfromhere I use LT for books, no DVDs etc (yet) and second the recommendation! No idea if less popular media such as LD, VD or video tapes are supported, but the people behind LT are incredibly helpful and open for suggestions.
Note that it doesn't work with Jellyfin.
I don’t actually have Jellyfin set up yet (just subscribed to keep track of an interesting project I might use someday). With it not being integrated, do you mean this just ends up being duplicative? Or that it doesn’t auto-import into LT from Jellyfin so you have to manage that manually?
