Well, since I'm currently engrossed in the Warhammer 40K universe, there's some long series there.
The Horus Heresy series - 19 novels, 18 short stories and 4 novellas.
The Gaunt's Ghosts series - 13 novels, a short story anthology and an audio book.
The Eisenhorn and Ravenor series - 7 novels and 5 short stories.
