Back on the subject of GRE Lit preparation:
In part because I'm neurotic, in part because I'm desperate to realize some kind of gain from all my hard work (no PhD programs for this year), and in part because I'm just so darn helpful (!), I've started posting all my GRE Literature flashcards at http://www.grelitblog.blogspot.com. I'll be posting a minimum of 1-2 cards per day, with links to information on or full online texts of all the works mentioned in each card.
Vade Mecum is also a great source, and the Princeton Review book was well worth the money.
