In the last few years, I've been trying to read whatever "modern classic" I hear about (if it interests me, of course). The Hitchhiker's Guide, Catch-22, Brave New World and stuff.
Or books I hear about here. The Gun Seller was great, for example
Also, I've been doing some reading on my iPod Touch, I read quite a few free ebooks, especially Lovecraft.
And I also read some sci-fi. I usually do some research on the internet before, then decide on a book. Or in the case of my current book, Do Android's Dream of Electric Sheep, it's because I love Blade Runner so much, I wanted to read the book
