you can include the entire run of the Original novels. I think it goes to 13 or so, with the last 2 or three being original stories (the rest are adaptations of the series) The current Dynamite Comics can fit in (although people disagree on the quality of the stories, and the time traveling one ruffled feathers with the inclusion of Dr Zee)

I personally concider the Hatch novels (all ghost written) to be a proper continuation. I don't agree with everything in them, but it's decent and all based on the original series. This would discount the Maxim (Could have the name wrong) Comics which were a future storyline. I would also include the events hinted to in the Second Coming trailer.
