The annual threads on HN about, "What was the best book your read in $YEAR", tend to have some brilliant books that I would have never encounted any other way.

The annual threads on HN about, "What was the best book your read in $YEAR", tend to have some brilliant books that I would have never encounted any other way. Bill Gates annual list tends to be solid as well, but only a handful of books each time. Mark Zuckerberg's reading club could potentially be useful too. I still find a lot of success in just going to a second hand book store and finding gems in a fairly short amount of time too. But obviously more niche books are unlikely to be there. Goodreads, does tend to be fairly good at identifying authors of a similar theme, but that has only been of limited usage to me.
