GoodReads - books and non-Japanese comics (...because listing all the volumes of manga I've read would take forever, and I have a MAL to keep track of my manga)
HowLongToBeat - video games
Letterboxd - movies
MyAnimeList - anime and manga
Visual Novel Database - visual novels, because HLTB doesn't have all of them...
The only base I don't have covered is a place to track tv shows outside of anime. Anyone know of any?
