Literary References in Lost

This post is going to have heavy spoilers for the Lost season finale. If you haven't seen it yet, read ahead at your own risk.

The day after every episode of Lost airs I tend to head over to Lostpedia and read about the latest fan theories based on the information revealed in the most recent episode. One thing that I always find interesting is the literary references that they cram into every episode. Some of them are a stretch, but the sheer quantity of them leads me to think that most of them are not a mere accident. The one reference that I found on Lostpedia for the finale was the following:

The Lord of the Rings:The Fellowship of the Ring: Jacob's "They are coming" is the same phrase found in the Book of Mazarbul, found and read by the Fellowship in the Chamber of Mazarbul in Moria. Shortly after reading this account of the demise of the Dwarves of Moria, the Fellowship loses one of their company when Gandalf is dragged into a chasm by the whip of a Balrog, a scene which Juliet's own fall recalls.

That's really cool and even if it's an accident, it's interesting that someone was astute enough to make that connection.
