I consider "limited series" to generally be distinct from miniseries in that episodes air on a weekly basis, like a regular series, as opposed to two or more episodes within a week. It may be an arbitrary distinction, but it feels right to me. There may be other factors that go into which way I decide to classify a series, but that's the main one. Other websites, like Wikipedia, may do it differently, which is fine, I guess. But I don't usually let that influence my own judgement. It does get a bit dicier when I'm trying to decide how to classify, for example, a British serial, but I usually try to use the same criteria that I do for American shows, whenever possible. (Though British limited series often have fewer episodes than American limited series.) Also, sometimes a series may be announced as a "limited series", and then get renewed for one or more subsequent seasons. In some cases I'll consider each season a limited series, if it's an anthology-by-season type of series, in which every season tells a completely different story (as is the case with "American Horror Story"). But if it's a continuation of the same story, I will no longer consider it a limited series. Further complications arise when I know the people making the series intend or hope for it to last longer than one season, but it gets cancelled after just one season. In that case, I usually won't consider it a limited series, but there may be exceptions. I dunno, it's all very complicated. I just do my best.
