If you're talking about TV cartoon shows, try a power search at the IMDb. Limit it to the genre "animation" and in section three, list "ONLY TV shows". There are close to 1800 shows listed alphabetically, from all countries.
Or, you could try the Big Cartoon Database.
Or this one, which limits it to Superhero cartoon shows.
This page, apparently from the same source, lists many more types of toon shows.
