I recognize it, I love science fiction. A few years ago, I started around the internet, checking a lot of lists about the bests sci-fi books and I created my own list of books that I would like to buy and read. I've almost completed my little collection and I'm writing a list with all of them. At the moment, is not fully complete and only contains the books I already read, so I will keep updating it!
You can find it on a Gist I created.
