Seriously, nobody?
The GRE is the graduate record examination. Almost all graduate programs in America (with the exceptions of medical and law school) require it.
Capacityplanner, I actually took mine last fall so it's fairly fresh in my mind. If you've only got a limited amount of time to study for it, I wouldn't recommend going around and reading pieces of actual literature. It is an ideal way of learning vocab, but only if you have an unlimited amount of study time. I recommend getting an actual GRE prep book with a vocab list in it and studying from that. The advantage is that they'll actually have practice tests so that you can see if you can apply what you learned.
I've heard really good reviews of the Kaplan's Verbal workbook. I didn't use it so I wouldn't know but you might want to check it out. Here's the link: http://www.amazon.com/Kaplan-GRE-Exa...6807178&sr=1-1
I used Barron's prep book (http://www.amazon.com/Barrons-GRE-Gr...6806893&sr=1-6), but I wouldn't recommend it. Although their vocab list is pretty comprehensive, there are actually some definitions which are wrong, and even occasional entries with NO definitions whatsoever. The editors did a bad job with this book. But you can check out the user ratings of many GRE prep books on amazon.com.
PS - what grad program are you applying to? I'm actually prepping to take my GRE in English lit in April.
