Getting back into Shadowrun (and Earthdawn), Which books to read and in what order? Options

[Ka_ge2020]

Okay, the last time that I played/GM'd Shadowrun was back in the days of SR2 (and ED1 for Earthdawn). As with many people I've got a lot on my plate at the moment but I want to get back into the game setting and, perhaps as more of an anecdote, the shared setting information between Earthdawn and Shadowrun. So, partially as a result of nostalgia, partially because I've been inspired by films and other game materials recently, I've come back to the fold (as it were).

So, the point of the thread. Beyond reading through SR4 core, what books and in which order would you recommend for someone coming back to Shadowrun and Earthdawn after several editions? I'm particularly interested in the overarching meta-story of Earthdawn/Shadowrun, so feel free to throw in novels as well as sourcebooks.

Please forgive any thread repetition. A quick search didn't reveal anything that matched what I was trying to get at but, well, familiarity with search terms and all that. Thanks for your input. (IMG:style_emoticons/default/biggrin.gif)
