I'm surprised how few books there actually are. Each time I see one of these lists I see the same books over and over again. In a single lifetime you can easily read all "good" books. Wonder what books are good but are hardly mentioned, probably none cause if they were good the would be mentioned. We have a tendency to think there is hidden knowledge but that is just not the case. These books are what there is kind depressing if you've read most of them.
It's probably isn't that few books surpass a measure of quality but how a hit based business is rate limited by the bandwidth of word of mouth trendiness.
