Note these are by default sorted by his rating. I really like his rating system, which he explains:

"My 0-10 rating is not just how much I liked the book. It’s how strongly I would recommend it to almost anyone. So I would give a little lower rating to a book I loved about an obscure subject, like the culture of Switzerland, because I wouldn’t recommend it to most people."

i.e. the rating is, roughly, how much it's likely to help you.
